Isaiah 53:5, "But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed."
Recently, I read about the healing ministries in the book of Acts. As always I was excited and amazed at the authority God gave to Peter and the boys! Can you imagine being so powerful that a person could be healed by being in your shadow? (Acts 5:15) Now that's power, and given to those considered very low in social status and education.
The healing that occurred in the early Acts days, occurred because the disciples were sourced by God, not by religious acts. They knew what "Jesus" meant, and they used His name in their lifestyle, not just their words. Because they were sourced by God, they healed the sick and raised the dead.
The Bible says clearly that faith in God makes you WORTHY. Faith brings about righteousness, not performance. Be sourced by relationship not your own performance, because standing on your own will lead to a fall. Notice the action packed healing ministries the Disciples had in place until chapter 15.
NB: Healing a very important part of Jesus’ ministry (healing and deliverance through the power of the Holy Spirit) had been common place in the early church, but has been largely overlooked or ignored in the modern church.
