Many people today still believe that God would punish them with some things, even that he would impose sicknesses on them that they have to carry as punishment. But the bible shows us a completely different picture.
But he was pierced for our transgressions, he was crushed for our iniquities; the punishment that brought us peace was on him, and by his wounds we are healed. Isaiah 53,5
The punishment is on Jesus, not on you! God never punishes you with sicknesses or anything else. It is important to know the difference between the old covenant and the new covenant. In the Old Testament beating and sickness were the consequence of disobedience and man’s rebellion against the law. The law worked in the way that blessing followed keeping the law and curse followed breaking the law. But today you live after the cross under the new covenant of grace. The cross makes all the difference.
God made him who had no sin to be sin for us, so that in him we might become the righteousness of God. 2 Corinthians 5,21
God made Jesus to be sin for you and me, so that you and I would become the righteousness of God in Jesus. Jesus took sin and its consequences upon himself and bore it representatively for us. He was the one who kept the law. He did what we could not do. Grace did what the law could not do. The law shows you what you do wrong, but it has no power to save you. Therefore, you need Jesus, your saviour.
Therefore, there is now no condemnation for those who are in Christ Jesus. Romans 8,1
As believer you are in Jesus and hence there is now no condemnation for you. This means that when you sin, you look to the cross, to what Jesus did for you. There is no punishment and no condemnation for you anymore because God put the punishment at the cross on Jesus. You are free! The knowledge of the punishment being on Jesus gives you peace. Thus, when your body is afflicted by a sickness, do not accept it. Keep in mind that the punishment and therefore also this sickness is on Jesus, not on you. Just say: “Thank you, Jesus, the punishment is on you, not on me. You bore this sickness. What you bore, I don’t have to bear anymore. Thank you, that you never punish me with sickness, but you have set me free from sickness. Amen.” Replace the lie, that God punishes you with sickness, with the truth, that God put the punishment on Jesus and set you free from sickness. God never punishes you! The punishment is on Jesus, not on you!
