The heart is deceitful above all things, and desperately sick; who can understand it? (Jeremiah 17:9 ESV)
I first heard the verse above at youth conference a long time ago. It made so much sense to me, so much sense of my own experience of life up to that point. I knew my heart was full of evil, but I was at a loss to figure it out. Everyone in my life kept telling me I was a great student, telling me I was a good kid, but the guy in the mirror told me a different story. But this verse told the truth. Underneath what looked like a good kid was heart that was full of wicked thoughts and deeds. Not only did I have everyone else fooled, but I fooled myself. My heart was desperately sick. That rang true to me. That’s why eventually the verse below (2 Corinthians 12:9) gave me so much comfort. It is still comforting to this day! I don’t have to understand my heart completely, and I don’t have to be fooled by it. What I need is to understand that God’s grace is sufficient to redeem me from the deceitfulness and sickness of my heart. So, like Paul in his letter to the church, I boast in my weaknesses that Christ’s power may rest on me.
But he said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” Therefore I will boast all the more gladly of my weaknesses, so that the power of Christ may rest upon me. (2 Corinthians 12:9 ESV)
