We, too, are all very sick until Christ heals us. We have this sinful nature we inherited.(Romans 5:12) Our symptom is not leprosy, but the sins we commit. (Rom. 3:23) Jesus healed us when we believed. Isaiah used that metaphor, saying "with his stripes we are healed". (Is. 53:5)
So, how do we respond? Are we falling at the feet of Jesus in worship, praise and thankfulness? Or are we going through the motions?
