1 Corinthians 12:28, Miracles and Healing
When Jesus was upon earth, he wrought the first miracle in Cana of Galilee. It was in a small village and it was during the wedding celebrations of a couple. Jesus turned water into wine. The gospel of John narrates to us in John 2:11 This beginning of miracles did Jesus in Cana of Galilee, and manifested forth his glory; and his disciples believed on him.
The manifestation of the miracles was for the purpose of pointing the people to Christ, the Son of God, the Giver of miracles, that they may find salvation in Jesus Christ. For that matter, when Jesus heals, it was to point us to believe on Him, the only Saviour of the world – John 14:6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
