How did Jesus prove to John the Baptist that He was the Coming One?
Jesus answered John’s disciples by pointing to His miracles: the blind received their sight, the dead were being raised, and the deaf received their hearing. These signs authenticated Him as the Coming One, the Messiah, proving He was indeed the Christ whom John expected.
Les explains that John the Baptist, while in prison, sent his disciples to ask Jesus, “Are You the One, or do we look for another?” Jesus told those friends of John to go back and report what was happening: the blind receive their sight, the dead are being raised, and the deaf are getting their hearing back. Les says that was to prove to John who He was, and all the way through the Gospels this is the proof that He was indeed the Christ. John 20:30–31 likewise notes that many other signs Jesus did in the presence of His disciples are not written in that book.
