Have you ever justified something in a way that you know made no sense – but it was the best you had in the moment? We have this very human tendency to use our mind to justify after the fact what our heart desired in the moment. We do things we feel like doing, then in hindsight we scramble to come up with reasons that at least seem good to us. We listen to our hearts, then tell our heads to justify our actions. “Follow your heart, listen to your heart” are mantras we hear in some form all the time.
The problem is that it's a bad philosophy of life. And since God is for us, and He cares about us enough to give us some insight into how we work and how life works, it’s no surprise that the Bible has given us some insight into why simply “following your heart” is a bad idea.The prophet Jeremiah records God’s message to the Israelites at a time when they had walked far from God. After telling them that those who trust in the strength of people are like bushes in a wasteland where there’s no water and the ground is sowed with salt, he makes a sharp contrast:
Blessed is the one who trusts in Me alone; the Eternal will be his confidence. He is like a tree planted by water, sending out its roots beside the stream. It does not fear the heat or even drought. Its leaves stay green and its fruit is dependable, no matter what it faces. (Jeremiah 17:7-9)
The person who trusts in God is grounded, fearless, and bears fruit, which is another way of saying that this kind of person is being everything he or she was made to be. Awesome! Jeremiah continues:
The heart is most devious and incurably sick. Who can understand it?” (Jeremiah 17:10)
Well. This seems like an abrupt change of thought. The context is that God is explaining how life in His path will bring life, but a life in rebellion to him will bring some serious trouble. The Septuagint says, "The heart is deep," a bottomless pit full of sin. Perhaps that is why Proverbs 28:26 warns us, “He who trusts in his own heart is a fool.” I am going to give us two principles to help us avoid the trouble lurking in our heart, and two principles to help us embrace the wisdom that comes from God.*
