The Bible uses the word heart as the center of the human personality—the inner person in contrast to the body. It is the spiritual side of the person, and it has three aspects: the mind, the emotions and the will. While we all share these three aspects, God has formed our personality and the events of and people in our lives style it, so that we are all unique people. But regardless of our individual form, God tells us truths that he intends to transform our inner person increasingly into his moral likeness. In other words, God wants to perfect the variety that he has designed in the womb and develops through the events and people of our lives. So let’s examine what he tells us about human hearts from this passage.
The Lord tells us the effect of a healthy heart (15:13). Every human is a functional unity of the outer person (the body) and the inner person (the heart or soul or spirit). Contrast this text with Psalm 42:3-5, where we see the depressing influence of a downcast heart. Depression leads to inactivity that breeds more depression and inactivity. It is a downward spiral.
Since we have this functional unity between the inner and outer parts of our humanness, the Lord encourages happiness of heart. In the words of John Trapp of long ago, “The heart sits smiling in the face and looks merrily out of the windows of the eyes.” However, we must clarify the Lord’s intent. The Lord wants us to have a happiness of heart that is based on proper principles (for example, Psalm 32:1-2). The Lord wants us to express our inner joy wisely and with a regard for the life situations of others (Romans 12:15; Proverbs 27:14).
Consider how the heart can create two very different effects. First, a happy heart will make you appear cheerful, and that shows up on your face. I recall two songs from years ago that sought to get this point across: “Take that frown off your face, put a smile in its place, let the love of Jesus Christ show through!” And, “Smile a while, and give your face a rest, raise your hand to the One you love the best, then shake hands with one nearby and greet them with a smile!” Those who are part of a local body of Christ should learn to read each other’s faces, and then prayerfully, boldly and gently seek to serve each other in love.
But second, heartache crushes the spirit—a person loses the desire to continue. What are some causes of heartache? Events like unfulfilled expectations, untimely or unexpected separation, and betrayal by one you love. Such happenings can pile up quickly, and we can feel shattered.
The way out can be difficult and long. The Lord Jesus Christ has provided ways to help you. He speaks to us through his word, providing us his perspective and counsel. For example, read out loud and listen to Psalm 119. It is a great prayer of a person enduring affliction. Let its words soak into you, and then pray them back to God our Father. Jesus has given us his Spirit, who desires to produce his fruit in us (Galatians 5:22-23). Think of each of those qualities, and ask the Spirit to refresh your heart with them. Christ has also placed us in groups of people who know him and love one another (1 Peter 1:22). You are with them to share life, and since they belong to Christ, they are equipped to help you (Romans 15:14). The Lord is forever faithful. Draw near to him; he wants you to have a healthy heart.
Grace and peace, David
