Transforming Shark Thoughts: Renewing Our Minds in Christ

Summary

So often, our lives can look picture-perfect on the outside—smiles, laughter, and a sense that everything is under control. But beneath the surface, in the depths of our minds, there can be swirling “shark thoughts”—those negative, anxious, or destructive patterns that threaten to consume us if left unchecked. Just as sharks are constantly moving, sometimes hidden, and drawn to blood in the water, our thoughts can be relentless, often hidden from others, and attracted to negativity and drama. Science tells us that our brains are wired to focus on the negative, but God, in His wisdom, has given us the capacity to change and heal our minds through neuroplasticity—the ability to rewire our brains.

God has not left us powerless in the face of these shark thoughts. He has given us His Spirit, His Word, and the responsibility to partner with Him in renewing our minds. Paul’s words in Romans 12 remind us that transformation comes through the renewing of our minds—a process, not a one-time event. This is an invitation to step into the ongoing work of becoming more like Jesus, to renovate our thinking, and to restore our minds to the way God intended.

Every thought we have affects and directs our lives. We are called to go beneath the surface and examine what we’re really thinking about. Are we partnering with the patterns of this world—pride, self-sufficiency, negativity—or are we aligning our thoughts with Christ? The process is practical: we must “reel in” our thoughts, become aware of them, “catch” and inspect them, “tag” and name them, and then “release” what doesn’t align with God’s truth, replacing it with His thoughts and promises.

This is not just about removing negative thoughts, but about creating space for God’s truth to take root. God’s thoughts are higher and better than ours, and He invites us to trust Him, to let go of what is not from Him, and to fill our minds with what is true, noble, and praiseworthy. Through the power of the Holy Spirit, we have the ability to change our minds and, in doing so, change our lives. Let’s be intentional neuroplasticians—actively partnering with God to shape our inner world so that our lives reflect His love, peace, and purpose.

Key Takeaways

- The hidden world of our thoughts shapes our reality. Just as children can smile for a photo while sharks swim behind them, we can present a happy exterior while dangerous thoughts swirl beneath the surface. Recognizing this hidden battle is the first step toward true transformation. [47:11]

- God has designed us with the capacity for neuroplasticity—the ability to change and heal our minds. This means we are not stuck with the thoughts or patterns we’ve always had; through the Spirit and the Word, we can rewire our thinking and experience real change. [53:19]

- Transformation is a process, not a quick fix. Paul’s call to “be transformed by the renewing of your mind” is an invitation to ongoing growth, learning, and becoming more like Jesus. This requires daily attention and intentionality, not just crisis management or Sunday routines. [56:59]

- We must actively engage with our thoughts: reel them in, catch and inspect them, tag and name them, and then release what doesn’t align with God’s truth. This practical process helps us discern which thoughts are from God and which are “shark thoughts” that need to be replaced. [01:06:59]

- Releasing negative thoughts is not enough; we must replace them with God’s truth. God’s thoughts are higher and better than ours, and as we fill our minds with His Word and stay close to Jesus, we create space for His peace and purpose to shape our lives. [01:11:20]

Devotional

Day 1: Be Transformed by Renewing Your Mind
God invites us into a process of transformation, not by conforming to the patterns of this world, but by renewing our minds and aligning our thoughts with His truth. This renewal is not a one-time event but a continual journey of becoming more like Jesus, allowing His Spirit and Word to reshape our thinking and, in turn, our lives. As we step into this process, we are called to renovate our minds, restoring them to the way God intended, and to trust that real change begins beneath the surface, in our thought life. [54:50]

Romans 12:2 (ESV)
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.

Reflection: What is one recurring negative thought you need to surrender to God today, asking Him to help you begin the process of renewing your mind in that area?


Day 2: Take Every Thought Captive
Every thought that enters our minds has the potential to shape the direction of our lives, but we are not powerless against them. God gives us the responsibility and the tools to reel in, catch, and inspect our thoughts, choosing which ones to keep and which to release. By taking every thought captive and making it obedient to Christ, we actively partner with the Holy Spirit to ensure our minds are shaped by truth rather than by the swirling negativity or lies that can so easily take over. [01:03:41]

2 Corinthians 10:5 (ESV)
We destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey Christ.

Reflection: What is one thought pattern you need to “catch” and examine today—does it align with Christ, or is it a “shark thought” that needs to be released?


Day 3: Guard Your Heart and Mind
Our lives are shaped by our thoughts, and everything we do flows from the condition of our hearts and minds. God calls us to be vigilant, to guard our inner life above all else, because unchecked thoughts can become powerful forces that direct our actions and attitudes. By paying attention to what we allow to dwell in our minds, we can protect ourselves from negativity and create space for God’s truth to flourish within us. [01:02:55]

Proverbs 4:23 (Good News Translation)
Be careful how you think; your life is shaped by your thoughts.

Reflection: What is one practical step you can take today to guard your mind from negativity and fill it with God’s truth?


Day 4: Filter Your Thoughts Through God’s Standard
Not every thought that comes to mind is worth keeping; we need a filter to discern which thoughts are true, noble, and life-giving. God provides us with a standard in His Word, encouraging us to meditate on what is true, honorable, just, pure, lovely, and commendable. By intentionally filtering our thoughts through this lens, we can tag and track what is shaping our inner world, choosing to dwell on what brings life and hope. [01:07:41]

Philippians 4:8 (ESV)
Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things.

Reflection: Which thought or emotion do you need to “tag” and filter through Philippians 4:8 today, and how might that change your perspective?


Day 5: Release and Replace with God’s Thoughts
It’s not enough to simply remove negative or harmful thoughts; we must also replace them with God’s higher and better thoughts. His ways and thoughts are beyond ours, and He invites us to trust Him by letting go of what is not from Him and filling our minds with His truth through prayer, Scripture, and closeness to Jesus. As we release the “shark thoughts” and create space for God’s perspective, we experience true transformation and peace. [01:10:09]

Isaiah 55:8-9 (ESV)
For my thoughts are not your thoughts, neither are your ways my ways, declares the Lord. For as the heavens are higher than the earth, so are my ways higher than your ways and my thoughts than your thoughts.

Reflection: What is one “shark thought” you need to release today, and what specific truth from God’s Word will you intentionally replace it with?

Quotes

How often do we pray prayers like, God, take this away. God, make these thoughts stop. God, change my desires, change my thoughts. And could he do all of those things? Yes, of course, because he's God. But will he, has he? Probably not because we're not robots and God's not a manipulating God. He's kind and he's gentle and God always, always, always does his part. But you and I have a part to play in this as well. [00:54:54] (00:00:32 seconds) Edit Clip

Because our lives are shaped by our thoughts. What we're thinking about really does matter. Paul says in 2 Corinthians 10, 5, we take captive every thought to make it obedient to Christ. He says in Colossians 3, 2, set your minds on things above, not on earthly things. God will always do his part, but we have to do ours. [01:01:32] (00:00:29 seconds) Edit Clip

Do you know that the goal in all of this, all of this life, this side of heaven is not to be happy? It's not to get what we want. It's not to be married and have kids. It's not to have wealth and success. Those are all great and okay and blessings from God. But the goal of all of this, the point of all of this is for every single one of us to pursue God with everything in us. The goal and point of this life, this side of heaven is to become like Jesus. It starts in our thinking. It starts in. our thoughts. It starts by us renewing our minds so we can be transformed into more of Jesus. [01:02:02] (00:00:53 seconds) Edit Clip

We use our powerful God tools for smashing warp philosophies, tearing down barriers erected against the truth of God. In other words, we use God's way of doing this to smash and to capture the shark thoughts that are tearing down the truth of God. And we fit every loose thought and emotion and impulse into the structure of life shaped by Christ. [01:06:07] (00:00:27 seconds) Edit Clip

We've got to release the shark thoughts. We've got to send them on their way so they don't take up space beneath the surface of our lives and our minds and take over. We have to release it so that we can replace it. So much of our life, we're trying to remove things, which is great. We've got to get the shark thoughts out, but that's not enough just to remove it. That's not, just removing it is not going to sustain us. We've got to actually replace it with God's thoughts. [01:09:57] (00:00:35 seconds) Edit Clip

God will always do his part. He is faithful to be trusted. But we have a responsibility. You are the neuroplastician of your life. Meaning God has given you the ability to rewire and change your life. We change our mind, we can change our life. And we have the ability by the power of the Holy Spirit to do it.
