Have you ever wondered why, even after giving your life to Christ, you still struggle with certain thoughts, emotions, habits, or desires?
Perhaps you genuinely want to forgive someone, yet resentment lingers. You desire peace, but anxiety overwhelms your thoughts. You long to exercise self-control, but old habits seem determined to regain their influence.
Shouldn’t living a victorious Christian life come more naturally once we’re born again? The answer becomes clearer when we understand how God created us and how His Spirit transforms us from within.
The Bible reveals that we are more than physical beings. We have an inner life that shapes how we think, feel, choose, and relate to God. Understanding the relationship between our spirit, soul, and body provides valuable insight into sanctification—the ongoing process of becoming increasingly Christlike—and how we grow in the fruit of the Spirit.
In 1 Thessalonians 5:23, the apostle Paul prays: “May God himself, the God of peace, sanctify you through and through. May your whole spirit, soul and body be kept blameless at the coming of our Lord Jesus Christ” (NIV).
Notice that Paul identifies three aspects of our being: spirit, soul, and body. This understanding, called trichotomy, describes humanity as consisting of three distinguishable yet interconnected parts.
Christian teacher Watchman Nee explored this concept extensively in The Spiritual Man, emphasizing the importance of living according to God’s Spirit rather than being governed by our natural desires. This framework offers helpful insight into spiritual growth.
Consider the three parts individually.
Our bodies allow us to interact with the world through our five senses: sight, hearing, smell, taste, and touch. Through them, we work, worship, communicate, and serve others. Yet our bodies also experience appetites, fatigue, and physical desires that can influence our behavior.
The body itself is not evil. God created it and calls us to honor Him through it: “Therefore honor God with your bodies” (1 Corinthians 6:20, NIV).
Our physical bodies are meant to become instruments of righteousness, expressing God’s love through our actions.
The soul encompasses our personality and the inner faculties we use to think, feel, and make decisions. Its three primary functions are:
Consider forgiveness. Your mind recognizes God’s command to forgive, yet your emotions remain wounded. Meanwhile, your will must choose whether to obey Scripture or continue holding on to resentment. This demonstrates why spiritual growth involves more than biblical knowledge.
Our thoughts, emotions, and decisions must increasingly align with God’s truth.
Paul writes in Romans 12:2, “Do not conform to the pattern of this world, but be transformed by the renewing of your mind” (NIV). Our thoughts many times drive our emotions and behaviors, which is why we are instructed to renew our minds with God’s word.
God doesn’t intend to eliminate our personalities or suppress our emotions. He desires to transform these faculties so they increasingly reflect Christ.
But if these two components were all we were, we would be as incomplete as the Godhead if it consisted only of God and Jesus. A third part of ourselves sets us apart as made in God’s image—our spirit.
Our human spirit is the innermost dimension of our being through which we relate to God. Watchman Nee identified three functions associated with the human spirit:
Jesus declared: “God is spirit, and those who worship him must worship in spirit and truth” (John 4:24, ESV), while Romans 8:16 tells us, “The Spirit himself bears witness with our spirit that we are children of God” (ESV).
Through our human spirit, we experience fellowship with our Heavenly Father, discern spiritual realities and gain insight, and determine right from wrong. However, spiritual discernment is not simply following feelings or impressions. We must test everything we perceive against Scripture and God’s character.
Here’s a helpful chart breaking down each aspect of our body, soul, and spirit. Can you already see how understanding this helps you in your sanctification journey?
| Body | Soul | Spirit |
|---|---|---|
| Made of: Ground/dust | Made of: Uniting of body and spirit | Made of: God’s breath of life (God-breathed) |
| Conscious of the physical world and worldly pleasures | Conscious of self (self-awareness) | Conscious of God (God awareness) |
| Uses five senses to interpret the physical world | Gateway between body and spirit; uses both senses and spirit to understand, feel, and act | Inner being that communicates with God |
| “Senses” dwell in the body | “Self” dwells in the soul | “God” dwells in spirit |
| Weakest—easily led astray by walking in the flesh | Most influential—determines if the flesh, self, or spirit rules; the soul has the will that decides which of these three will be MASTER. | Noblest—communicates with the spirit realm; conforms to Christ’s image |
Understanding our threefold nature becomes especially meaningful when we consider salvation. Before receiving Christ, we are spiritually separated from God because of sin. But when we place our faith in Jesus, something extraordinary happens: We become spiritually alive in Him!
Paul declares: “Therefore, if anyone is in Christ, the new creation has come: The old has gone, the new is here!” (2 Corinthians 5:17, NIV)
This new birth is more than a change in religious beliefs or improved behavior. It is a supernatural work of the Holy Spirit. The prophet Ezekiel foreshadowed this transformation: “I will give you a new heart and put a new spirit in you” (Ezekiel 36:26, NIV). Through regeneration, we enter a new relationship with God, and His Spirit comes to dwell within us. We can commune and fellowship with God, and the Holy Spirit speaks to our spirits, illuminating truths in His Word.
Yet our minds do not instantly become perfectly renewed. Our emotions may still carry wounds, and our bodies may respond to familiar temptations. This explains why sincere believers sometimes struggle with sinful attitudes, unhealthy habits, and misguided desires.
Regeneration begins our new life in Christ; sanctification is the continuing process through which that life transforms how we live.
Have you ever known what God wanted you to do but felt powerful resistance? Perhaps you wanted to respond gently during an argument, but anger rose within you. Or you knew you should trust God, yet your thoughts spiraled into fear.
Paul describes this conflict: “For the flesh desires what is contrary to the Spirit, and the Spirit what is contrary to the flesh” (Galatians 5:17, NIV). Here, the flesh refers to our fallen human nature and sinful inclinations—not simply our physical bodies.
Our natural tendencies may pull us toward selfishness, jealousy, resentment, or self-indulgence. Meanwhile, the Holy Spirit calls us toward righteousness, humility, love, and obedience.
This reveals an important truth: Not everything we think, feel, or desire should govern our lives.
Our emotions may be real without being reliable guides. Our thoughts may be persistent without being true. Our desires may be powerful without being beneficial.
Paul therefore commands: “So I say, walk by the Spirit, and you will not gratify the desires of the flesh” (Galatians 5:16, NIV). Walking by the Spirit means surrendering our thoughts, choices, attitudes, and actions to His leadership. As we consistently yield to Him, our character begins to change. When we walk by the Spirit, we submit our bodies as instruments of righteousness and our souls to His Lordship, so God is enthroned in our hearts. Speaking of which, what does the Bible mean when it talks about the heart?
If the soul contains our mind, will, and emotions, and the spirit enables communion with God, where does the heart fit? Throughout Scripture, the heart represents the deep inner center of our thoughts, intentions, desires, and moral decisions.
Within the threefold framework, we can understand the heart as encompassing our soul’s faculties together with our conscience.
Proverbs 4:23 urges: “Above all else, guard your heart, for everything you do flows from it” (NIV).
Consider how an unguarded heart affects spiritual growth. When our minds dwell on offenses, bitterness takes root. When we continually surrender our wills to temptation, unhealthy habits become entrenched. When emotions govern every decision, instability follows. And when we repeatedly ignore our conscience, we risk becoming less sensitive to God’s correction.
That is why David prayed after he sinned against God: “Create in me a pure heart, O God, and renew a steadfast spirit within me” (Psalm 51:10, NIV). David understood that lasting transformation requires more than changing outward behavior. He needed God to renew him from within.
A pure heart is not one that never experiences temptation, grief, or conflicting emotions. It is a heart increasingly surrendered to God—honest about sin, responsive to correction, and eager to obey.
Jesus said: “I have come that they may have life, and have it to the full” (John 10:10, NIV). The Greek word translated life is zoē, referring to life in its fullest sense. Through Christ, we receive eternal life, and His life transforms us from the inside out. Regarding our threefold nature:
We might picture this as the Holy Spirit working within our regenerated spirit, renewing our soul, and influencing how we act through our bodies.
As God’s truth reshapes our minds, our perspectives change. As we surrender our wills, our decisions increasingly reflect His purposes. As our emotions mature, we respond to challenges with greater faith and stability.
Our outward actions gradually reveal the inward work of grace. This is how the fruit of the Spirit becomes evident. Galatians 5:22-23 identifies nine qualities: love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control.
These are not merely personality traits or virtues we develop through human effort. They are the fruit of the Holy Spirit working within us. Consider how this appears in everyday life:
These virtues reflect the transformation that occurs as Christ’s life increasingly governs our whole being.
We do not produce spiritual fruit merely by trying harder to appear Christlike. We bear fruit by abiding in Christ and allowing His Spirit to transform us.
Jesus makes this clear: “If you remain in me and I in you, you will bear much fruit; apart from me you can do nothing” (John 15:5, NIV).
This is why we developed the Fruit of Faith Series. This nine-volume series helps us understand the fruit God wants to cultivate in us, identify what hinders that fruit in our lives, and work with the Holy Spirit to experience freedom, healing, and growth in our character as we become more Christlike. The first book in this series, Enduring Patience, will be released next year. Until then, our Fruit of Faith Blog will continue to provide insightful, practical, and instructive articles about growing in your faith.
In our next blog, we will discuss practical ways that understanding our threefold nature helps us to cooperate with the Spirit in developing the fruit of the Spirit!
