“The heart is deceitful above all things, and desperately sick; who can understand it?” (Jeremiah 17.9).
It seems like such a negative idea to call the heart “desperately sick.” Before the Fall when humanity allowed sin to enter the world, God created our hearts in His image and they were good (Genesis 1.27 & 31). But sin is death, and it corrupts everything–both physically and spiritually (1 Cor. 15.21). Many people like the thought that we are born perfect into this world, and it is society that corrupts us. However, the Bible explains that we are all born sinners, separated from a Holy God (Romans 3.23). There is hope, though, through the work of Jesus Christ on the cross. Yes, we fall short of the glory of God, but Jesus died to give us His righteousness (Romans 3.22). He transforms our corrupted hearts into new hearts that love Him (Ez. 36.26). Without Jesus, our hearts will deceive others and even ourselves. And when we hide areas of sin from the revealing work of the Holy Spirit, the sickness and darkness will continue to poison our entire lives. We can allow God full access to our hearts–the beautiful and the ugly–knowing that He loves us no matter what and nothing surprises Him. Once the Holy Spirit has full reign of our hearts, He will begin the process of transforming us into the perfect image of Christ from glory to glory (2 Cor. 3.18).
“And he who searches our hearts knows the mind of the Spirit, because the Spirit intercedes for God’s people in accordance with the will of God” (Romans 8.27 NIV).
