The Heart - Part 5 (Mind) - Derrick Harrison

Devotional

Day 1: The Mind is Formed by the Word of God.

The mind is not merely a function of the brain but is the center of our being, our soul. It is where our thinking, understanding, and love originate. This inner life is profoundly shaped and renewed by the truths found in Scripture. To mature in faith and develop a Christ-like character, we must allow the Bible to have a powerful and continual impact on our thoughts and actions. [13:33]

All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work. (2 Timothy 3:16-17 ESV)

Reflection: What is one practical habit you could establish this week to give Scripture a more regular and formative place in your daily life?

Day 2: Scripture is a Precious and Personal Treasure.

The Bible is not just another book; it is the living and eternal word of God. It is meant to be a personal and precious possession, a book we interact with, mark up, and make our own through study and reflection. When we engage with it personally, we give God an opportunity to speak directly into our lives, revealing His character and His truth in profound ways. [24:41]

I have stored up your word in my heart, that I might not sin against you. (Psalm 119:11 ESV)

Reflection: In what ways have you treated the Bible as a formal text rather than a personal letter from God? How might you approach it differently to hear His voice more clearly?

Day 3: The Knowledge of God is Incomparable and Humbling.

There is no knowledge in this world that compares to knowing God. His greatness, majesty, and perfect understanding are beyond our full comprehension. When we truly encounter Him through His Word, we are rightly humbled, realizing our own smallness and His overwhelming greatness. This humbling is a wonderful and necessary part of drawing near to the Almighty. [29:18]

I had heard of you by the hearing of the ear, but now my eye sees you; therefore I despise myself, and repent in dust and ashes. (Job 42:5-6 ESV)

Reflection: When was the last time you were truly humbled and awestruck by who God is as revealed in Scripture? What attribute of His character most captures your wonder right now?

Day 4: God's Word Nourishes Our Inner Life.

Scripture is the essential nourishment for our soul, much like daily food is for our body. It feeds our devotional life, guiding our path and lighting our way. The Psalms, in particular, provide a language for our deepest emotions and prayers, teaching us transparency before God. Making time for the Word is not a duty, but a vital sustenance for a healthy spiritual life. [31:52]

Your word is a lamp to my feet and a light to my path. (Psalm 119:105 ESV)

Reflection: Which area of your inner life feels most in need of nourishment—your emotions, your thoughts, or your will? How could specific passages from the Psalms speak into that need today?

Day 5: Loving God Engages the Whole Heart and Mind.

The greatest commandment calls us to a wholehearted love for God that engages every part of our being. This love is not a fleeting emotion but a deliberate commitment of the mind, soul, and strength. It begins with knowing Him through His Word, which in turn fuels a deep, understanding, and obedient love that defines our relationship with Him and with others. [22:51]

And you shall love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength. (Mark 12:30 ESV)

Reflection: Considering the command to love God with all your mind, what is one truth from Scripture you could intentionally meditate on this week to deepen your love for Him?

Sermon Summary

The human mind takes priority in spiritual life: intellect, emotion, and will belong to the heart — the soul — and Scripture must shape that inner life. The Bible supplies the vocabulary for thinking about God, morality, and holiness; knowledge without Scripture leaves the mind impoverished. Reading the Bible daily builds understanding, and understanding applied as wisdom changes behavior and sanctifies the heart. The sequence matters: acquire knowledge through Scripture, press into understanding so truths land in the inner life, then let wisdom govern decisions and relationships.

Personal devotion to Scripture proves decisive. Lifelong habits of reading, noting, and meditating produced formation, consolation, and vocational direction. Regular engagement with the Psalms feeds devotional affection; disciplined study of law, prophecy, and gospel forms doctrinal clarity. The testimony of childhood Bible reading and of turning to Genesis in grief illustrates how Scripture opens eyes, steadies memory, and sustains vocation.

Scripture shapes communal and moral practice. Deuteronomy’s command to love God with all heart and to love neighbor grounds all Christian duty; the New Testament affirms and extends that ethic into mutual love among believers. The Bible reveals exemplary leaders — Moses, David, Solomon, Paul — not as models of perfection but as sources of law, worship, wisdom, and apostolic mind. Paul’s claim that believers may share the mind of Christ challenges ordinary thought patterns and calls for spiritual formation that aligns convictions with Christlike judgment.

Knowledge of God remains vast and awe-inspiring. Job’s encounter with God models humility before divine transcendence: true knowledge fosters reverence, not presumption. The mind that rests in God’s omniscience finds safety and the humility to repent and learn. Practical counsel follows: adopt a reading program, use a Bible one can mark and return to, and cultivate the habit of hiding God’s word in the heart so it re-shapes speech, choices, and pastoral imagination. The ultimate aim is a Christlike mind formed by persistent Scripture reading, meditative prayer, and the Holy Spirit’s renewing work.

Key Takeaways

1. Scripture forms Christian knowledge Scripture supplies the categories and vocabulary by which the soul learns who God is and what holiness requires. Without regular Scripture, knowledge fragments into opinion and culture-driven ideas; the Bible anchors truth claims and reorients desires toward divine realities. Reading Scripture repeatedly lets doctrine become lived conviction, not just intellectual assent. [04:05]
2. Mind lives in the heart Thought, affection, and moral response originate in the heart — the soul — not merely the brain. Recognizing the mind as heart-centered shifts spiritual formation toward practices that address desire and will, not only cognitive assent. True transformation engages memory, imagination, and affections as well as reason. [01:47]
3. Knowledge, understanding, wisdom ordered Knowledge gathers facts from Scripture; understanding grasps how truths interrelate; wisdom applies them rightly in life. Spiritual maturity requires moving inward from data to meaning, then outward into wise action that reflects God’s character. This sequence prevents sterile information and produces sanctified choices. [03:43]
4. Daily Bible reshapes thinking Consistent reading, note-taking, and meditation train the mind to think with God’s categories and to see life through redemptive frames. Regular exposure to Scripture rewrites memory, reforms conscience, and supplies patterns for prayer and decision. Long-term practice produces resilience in suffering and clarity in vocation. [11:12]

And the Bible has a powerful impact. Paul speaks about the renewing of our mind. Our vocabulary, our thinking is formed by scripture. You neglect scripture and you're in trouble. You really are because you cannot mature in God's grace and life and maturity without the Bible having a powerful, powerful impact on your life. [00:12:55] (45 seconds) #RenewYourMind
