'But He was wounded for our transgressions, He was bruised for our iniquities; The chastisement for our peace was upon Him, And by His stripes we are healed. NKJV
We need to come to the knowledge that when God laid our sin on Jesus, Jesus took them away, even the problem of sickness and diseases in our lives, we do not have in anyway be dominated by sickness anymore
“who Himself bore our sins in His own body on the tree, that we, having died to sins, might live for righteousness — by whose stripes you were healed.” 1 Peter 2:24
We should have it printed in our hearts; ‘by His stripes we are healed’. As we have it printed in our hearts, we should agree and believe the truth in our hearts that by His stripes we are healed.
You have to be saying it with your mouth just as you are saying it in your heart. You have to believe the truth that you are healed. Say it, believe it, and act it. I want you to know that the Word of God is living, and the Lord will watch over His Word to perform it.
