Matthew 14:34-26 . Is the main point faith or is it that Jesus could heal ?

Repentance was also part of healing. Jesus often said to go and sin no more. Faith only has clarity and power within forgiveness. We cannot be brought to our true state of Sonship if we hold grievances and judgment against others. Believing in Jesus is the same as believing we are also God's sons. He told us that as well. Our true identity must be realized to be healed.
