How do you renew your mind for peace as a mom? Welcome back to Discovering Home. I'm Carla B. Monterrosa, author, speaker, and coach. Eight years ago, I left my full-time career to embrace my calling at home. And now I help working moms who desire more peace, presence, and purpose do the same. On today's episode of Discovering Home, I'm sharing my journey of breaking free from destructive thought patterns and learning to renew my mind through God's Word. Plus practical ways you can invite peace into your heart, your marriage, and your home. Let's get into it. In 2017, I left a full-time career in city government to embrace my calling at home. What started as a pause for my career became a decision to fully embrace my faith, motherhood, and a life of ministry. God brought me out of a full-time government career that didn't leave much room for my faith or family and gave me so much more. The transition wasn't easy, but it was life-changing. Because when God calls you to surrender a thing, he always intends to give you something better. In 2019, I published Unbraided, which is my testimony of overcoming childhood trauma through faith in Christ. As a result of writing that book, God completed a miraculous work in me. Not before it, but through it. Faith in action produces powerful results. I'm a different woman, wife, and mom today than I was before I said yes to that call. When I started writing, I thought I was already healed from the deep emotional wounds from my childhood. I saw my personal, academic, and professional successes as evidence of a healthy life. In reality, I continued to struggle with flashbacks and shame over what had been done to me and some of the choices I made as a result. The day my first daughter was born, I knew motherhood was going to be very difficult. I saw her little body and was reminded of how innocent and vulnerable they are. Every diaper change, bathtime, and bedtime, I struggled with intrusive thoughts. I remembered my abuse and knew that I had to protect them at all cost. It was exhausting and isolating. I was on the defense all the time. I didn't trust anyone. Eventually, what materialized in my mind was a terrible fear that I could be a danger to my own children. I knew I could never harm them, but was unable to stop the thoughts from intruding. Too ashamed to voice these thoughts aloud, I struggled in secret. Not even my husband knew I was having this internal struggle with the thoughts that continued to haunt and accuse me. Writing a book about my deepest pain and its consequences was how God led me to his deep and eternal healing. What I thought I would give to others was a gift that God gave me first. As a Christian woman, I knew I wanted my book to be full of biblical encouragement and practical wisdom. I spent countless hours praying over the assignment I was being called to, studying the Bible and writing down the details of my past. God used my book writing journey to reveal the wholeness that Christ purchased for us on the cross. Hebrews 10 verses 14 through 17 says, For by a single offering he has perfected for all time those who are being sanctified. And the Holy Spirit also bears witness to us. For after saying, This is the covenant that I will make with them. After those days, declares the Lord, I will put my laws on their hearts and write them on their minds. Then he adds, I will remember their sins and their lawless deeds no more. I read the scripture and realized that he already set me free. He had already taken my sins, shame, and pain upon himself on the cross, but I hadn't understood it. I continued to allow the enemy to accuse and oppress me with my past. The scripture clearly says that he has perfected us for all time, those who are being sanctified. That means he has already set us free. We are at war with our own thoughts and memories. It's difficult to break free from the bondage of recurring thoughts, counseling, self-help practices, academic or career pursuits, and the disguise that we put on to appear normal and whole to the world while we're hiding our true selves are at best useful tools and at worst, mere distractions from the pain and shame without Jesus. The memories of my painful experiences used to rise up in moments of stress. I would let myself linger there, replaying them, feeling them all over again, and before long, those thoughts began shaping my emotions and even how I treated the people around me. That cycle of negative thinking became a habit I needed to break. It was distorting how I saw myself, how I treated my husband and children, and even how I showed up in my career. How many of us do that without realizing? We get stuck ruminating on something our husband said or did that hurt us. Sometimes he meant no harm, sometimes maybe it was intentionally, but we turn it over in our minds again and again. We rehearse comebacks, we relive the sting, we arm ourselves with words to use the next time we're hurt. And by the time he walks through the door, we're already angry and ready to battle. I'm not judging, I speak from experience. I've been there. This pattern, letting my thoughts dictate my emotions and spill out into my actions, had been with me since I was young. Changing it wasn't easy, but I learned something life-changing. If we want our lives and relationships to look different, we must learn to take our thoughts captive and renew our minds. We must learn to dominate our thinking. 2 Corinthians 10 verses 3 through 5 says, For though we walk in the flesh, we are not waging war according to the flesh, for the weapons of our warfare are not of the flesh, but have divine power to destroy strongholds. We destroy arguments and every lofty opinion raised against the knowledge of God and take every thought captive to obey Christ. We must go to war in our minds against the thoughts and ideas that try to destroy us, accuse us, and steal our joy. I had to learn to renew my mind, to take my thoughts captive and make them obedient to Christ. Everything we do begins as a thought we build in our brains. The words we speak, the choices we make, the way we show up in our homes, they all take root first in our thinking. Neuroscientists have found that it takes approximately 21 days to form a long-term memory and another 42 days for that memory to become a habitual thought pattern. What we dwell on literally shapes the pathways in our brain. That's why we must be so careful about which thoughts we allow to stay. Our experiences are physically recorded in our brains. As Dr. Caroline Leaf explains in Think, Learn, Succeed, memories actually take physical space in the brain. The more we rehearse a thought, whether it's hope-filled or destructive, the more it grows, establishing patterns we will later operate out of automatically. So if we want a different life, a different marriage, a different atmosphere in our home, we must start by fighting for a different way of thinking. Renewing your mind is a form of spiritual warfare, but you must know the enemy's tactics. Grab hold of your armor and step into the battle with faith. Romans 12.2 says, Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect. This means it's possible to be transformed by renewing our minds. And we do this by taking every thought captive and making it obedient to the truth of the scriptures. Our minds are a battlefield. The enemy works to plant lies that shape our lives, actions, and relationships, and it can begin at a very young age, but we can combat those thoughts with God's truth. John 8, verses 31 through 32 says, If you abide in the Word, you are truly his disciples, and you will know the truth, and the truth will set you free. John 10 10 says, The thief comes only to steal and kill and destroy. I came that they may have life and have it abundantly. 1 Peter chapter 5, verse 8 says, Be sober-minded, be watchful. Your adversary, the devil, prowls around like a roaring lion, seeking someone to devour. And John 8 44 calls him a murderer and a liar. It says he was a murderer from the beginning and does not stand in the truth, because there is no truth in him. When he lies, he speaks out of his own character, for he is a liar and the father of lies. He accuses brothers and sisters day and night, according to Revelation 12.10. He whispers lies about our worth, our past, and our futures. He keeps us chained in old labels and wounds and uses us to accuse others. He looks for opportunities, unguarded thoughts and unhealed pain, exploits moments of stress, fear, or weakness to plant his lies. So be alert, resist him and stand firm in your faith. His goal is always destruction. He comes to seal your peace, kill your hope, and destroy your purpose. Ultimately, he would like to take your soul. But you are not helpless against this enemy. The Lord has given you Jesus, his spirit, and his word. But remember that the lies that go unchallenged become mental strongholds out of which the enemy can operate and attack in your own mind. What we repeatedly think about becomes the path we automatically take. The enemy wants to keep that path lined with lies, but God wants to rewrite it with truth. I believe that we hold on to our bad habits in certain seasons because they are serving us. When I responded out of bitterness, anger, and rage towards my husband, I was using my past as a crutch to justify the bad behavior that I was engaging in. I was treating him unfairly and I needed to change. But first, I needed to change the way I thought about my past. My reactions were not just, I am what I am because of what I experienced, and now I am entitled to be rude and disrespectful. Those were responses to my past wounds that were so deeply ingrained in my mind that I really needed God's help to change. I prayed, God, help me to change. I need you to heal me, transform my mind and heart, and help me to be different. Help me to reflect the grace of Christ in my marriage, in my home, with my children, and with others. I had to think better thoughts. That was a choice I needed to make, to reshape how I saw things. Ephesians 6, verses 13 through 18 says, Therefore, take up the whole armor of God, that you may be able to withstand in the evil day, and having done all to stand firm, stand therefore, having fastened on the belt of truth, and having put on the breastplate of righteousness, and as shoes for your feet, having put on the readiness given by the gospel of peace. In all circumstances, take up the shield of faith, with which you can extinguish all the flaming darts of the evil one, and take the helmet of salvation and the sword of the Spirit, which is the Word of God, praying at all times in the Spirit with all prayer and supplication. To that end, keep alert with all perseverance, making supplication for all the saints. He has given us the spiritual tools to fight the spiritual battle, to reshape our thinking and transform our lives. The Bible says it over and over again because He has equipped us and empowered us, we just need to grab hold and be obedient to that truth. I repented from my unjust treatment toward my husband and others. I learned to pause, breathe, pray before responding, and replaced reactive habits of thinking with the word of God. Ephesians 4, verses 31 through 32 says, get rid of all bitterness, rage, and anger. Be kind and compassionate. Peace at home and beyond begins by first embracing the forgiveness that God has given us and choosing daily and repeatedly to extend grace to others. If you're in a situation right now where your marriage is plagued with disharmony, you can't operate in peace and unity in your marriage without first renewing your mind. It's a process and you're not going to do it perfectly. Even when you've surrendered your life to Christ, picked up the word and put on your spiritual armor and are walking by faith in obedience, you will still have moments of weakness. Jesus calls us to repentance daily. So if you have a bad day or a bad moment, just know that you can begin again and again. His grace is that good. If you find yourself thinking negatively about your husband repeatedly, choose in that moment to fight for him. Refuse to partner with the enemy as the accuser of your husband. Be grateful for all of his wonderful qualities and pray for him. Remind yourself of how blessed you are to have a husband who loves you. They are such a gift from God. Make it a habit to bless him in your mind instead of cursing him. Daily renew your thoughts through prayer, studying the word, and meditating on scripture. If you're stuck in a negative thought pattern, fill that mental space with something that brings you joy. Listen to worship music, take up a hobby, create something beautiful, or learn a new skill. Guard the atmosphere of your mind and your home. Home should be a refuge from the chaos of this world, the safest place for your children to grow. Replace anger with grace, fear with faith, and practice self-control. So as we close today, I'm gonna leave you with a question. What thought patterns or triggers have been running unchecked in your life? God has led you here because he wants to heal you and retrain your mind for victory. Isaiah 26, 3 says, You will keep in perfect peace those whose minds are steadfast because they trust in you. God is faithful, his word is true, and you can trust him. I hope this message blessed you, and if God revealed some areas of your mind that need renewal, I pray that God will give you the strength to do battle, armed with the spiritual weapons God has given you.
