Our redemption was accomplished two thousand years ago and all of the benefits of that redemption became available at that time for all who believe. We have been freed from the power of sin and all of its manifestations, including sickness.
We can find God’s heart to see His people healed in many scriptures in both Old and New Testaments. God reveals Himself in one of His redemptive names as the God who heals us (Ex. 15:26). God’s nature cannot change so if He was a healer before the Law and under the Law, how much more under grace!!
Isaiah prophesied and Peter confirmed that by Jesus’ stripes we were healed. (Isa. 53:4-5, 1 Pet. 2:24) In other words, forgiveness exists for all men whether they receive it or not. The price was paid. And thus, healing is also available to all, though many do not take advantage of it.
Jesus revealed the will of God (Heb. 10:7) in His ministry when He went about healing all (Acts 10:38).
Jesus commissioned the church to heal the sick (Mark 16:18), and we see the early church walking in this power.
James asks if any among the church is sick (James 5:14). The very question implies that there should be no sick among us, and the necessary steps to receive healing are given.
Healing was accomplished on the cross and is available to all men, just as redemption from sin is available to all men. As we are transformed by the renewing of our minds and we walk in the authority and revelation of this great truth, we will be able to appropriate what Christ has purchased for us with His stripes.
