The sin of Judah is written with a pen of iron; with a point of diamond it is engraved on the tablet of their heart —Jeremiah 17:1. Our heart is affected by the sin we commit. We need help in obtaining a healthy heart. A bypass or medicine will not do the job, we need a complete transplant! God says, “ I will give them a heart to know that I am the LORD, and they shall be my people and I will be their God, for they shall return to me with their whole heart” Jer. 24:7. God knows we need Him and His forgiveness. Jesus claims to be a surgeon/physician for our heart. Matthew, Mark & Luke all record the same claim, “Those who are well have no need of a physician, but those who are sick. I have not come to call the righteous but sinners to repentance.” Mt.9:12-13, Mk.2:17, Lk.5:31-32.
Jesus told the parable of the unforgiving servant to teach us that we must forgive from the heart, as God forgives from His heart. Mt. 18:23-35. The fact is, a sinful heart can not forgive like Christ forgives, unless it is born anew. Forgive each other as Christ has forgiven you, Eph. 4:32
Heb 10:19-23 Therefore, brothers, since we have confidence to enter the holy places by the blood of Jesus, by the new and living way that he opened for us through the curtain, that is, through his flesh, and since we have a great priest over the house of God, let us draw near with a true heart in full assurance of faith, with our hearts sprinkled clean from an evil conscience and our bodies washed with pure water. Let us hold fast the confession of our hope without wavering, for he who promised is faithful.
Just as surely as the blood of Christ given 2000 years ago can not touch our physical hearts, neither can it purify water in a baptistry or muddy river. But by faith, we trust God’s promise in the blood to cleanse our spiritual heart, renewing us, our WHOLE being. Then, and only then can we be presentable and accepted by God as a new creature. 2Co 5:16-17, From now on, therefore, we regard no one according to the flesh. Even though we once regarded Christ according to the flesh, we regard him that way no longer. Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come. Today when someone becomes a Christian, they are operated on, Col. 2:11-12, in the operation of God, their heart is circumcised by Christ. After the work of God initiates a new creation, He then gives himself as a personal trainer, to help us maintain and grow the fruit of the Spirit.
He has come to live with us in the Spirit of Christ, He says through the prophet Jeremiah and the apostle Paul, “I will put my law within them, and I will write it on their hearts. 2nd Corinthians 3:3 & Jeremiah 31:33.
