Why the Affections Matter
What captures your heart?
It's a question we don't often ask ourselves, yet it may be one of the most important questions in the Christian life. We often evaluate ourselves by what we know, what we believe, or even what we do. But Scripture repeatedly directs us to something deeper: our affections.
Our affections reveal what we truly love, what we treasure most, what we trust, and ultimately what we worship. They expose the deepest desires of our hearts.
If we keep asking "Why?" behind every decision we make, we eventually arrive at the same answer: we want to be happy. Every person pursues what they believe will bring satisfaction. The tragedy is not that people seek happiness, it is that they seek it in places that can never ultimately satisfy.
Solomon recognized this reality when he wrote, "He has made everything beautiful in its time. Also, he has put eternity into man's heart..." (Ecclesiastes 3:11). God has created us with desires that extend beyond the temporary things of this world. We were made for Him.
Yet because of sin, our affections become misplaced. We chase careers, relationships, possessions, success, comfort, approval, or pleasure believing they will finally satisfy our souls. While many of these things are good gifts from God, they become dangerous when they replace God Himself as our greatest treasure.
David understood where lasting joy is found. In Psalm 16:11 he writes, "In your presence there is fullness of joy; at your right hand are pleasures forevermore." Jesus echoed this truth when He told His disciples, "These things I have spoken to you, that my joy may be in you, and that your joy may be full" (John 15:11).
Only the presence of God provides joy that cannot be shaken by changing circumstances.
This is why our affections matter!
The things we pursue reveal what we truly treasure. How we respond in suffering reveals what we treasure. What we do with our time, money, and abilities reveals what we treasure. Our lives are constantly exposing the deepest loves of our hearts.
Jesus made this reality unmistakably clear. Following Him requires loving Him above every earthly relationship, even above our own lives (Luke 14:26). Christ is not calling us to hatred in the ordinary sense but to such supreme devotion that every other love appears secondary in comparison.
Throughout Scripture we see both the danger of misplaced affections and the beauty of rightly ordered ones.
Eve desired the forbidden fruit more than obedience to God. Cain loved his own pride more than his brother. Abraham feared man more than he trusted God. David desired Bathsheba more than holiness. Judas treasured money more than Christ.
Each sinful action began long before the outward behavior. Sin first took root in the affections.
Jonathan Edwards famously described the affections as "the springs of men's motion." In other words, our affections drive everything we do. Knowledge alone does not move people into action. Love does. Fear does. Hope does. Desire does. Our hearts propel our lives.
This is why Christianity is never merely intellectual.
The Christian faith certainly involves truth. We are called to know God rightly. Jesus Himself defined eternal life by saying, "This is eternal life, that they know you, the only true God, and Jesus Christ whom you have sent" (John 17:3). But biblical knowledge is far more than collecting information. It is relational, personal, and intimate.
Jesus says in John 10 that He knows His sheep and His sheep know Him, just as the Father knows the Son. This kind of knowing transforms the heart.
True religious affections are not shallow emotional experiences that come and go with circumstances. Neither are they emotionalism divorced from biblical truth. Rather, they are the deep, abiding inclinations of a renewed heart that genuinely loves God and delights in His glory.
These holy affections also provide evidence of genuine salvation.
The writer of Hebrews commends believers for demonstrating love toward God's name by serving His people (Hebrews 6:9–10). Likewise, the Apostle John teaches that it is impossible to claim to love God while hating fellow believers (1 John 4:20–21). Genuine love for God inevitably expresses itself in love for others.
Our affections also reveal the condition of our souls.
"We love because He first loved us" (1 John 4:19). God's saving love awakens our love for Him. Jesus then tells us, "If you love me, you will keep my commandments" (John 14:15). Obedience is not the means of earning God's love but the fruit of having received it.
As believers mature, their desires begin to change. They increasingly love what God loves and hate what God hates. Though this transformation is often gradual, it is real. Wherever genuine faith exists, holy affections will eventually become evident.
Perhaps one of the most helpful questions we can ask ourselves is simply this:
What do I treasure most?
The answer will reveal far more than our words ever could.
May we continually ask the Holy Spirit to reorder our hearts so that Christ becomes our greatest joy. As our affections are shaped by His grace, our obedience becomes joyful, our worship becomes sincere, and our lives increasingly display the beauty of the gospel.
Christianity is not cold intellectualism, nor is it emotionalism without truth. It is a heart captivated by the glory of Christ, a life where the deepest affections belong to the Savior who first loved us.
