Christ did miracles to authenticate His claims to be the Messiah. John called these supernatural acts “signs”-events intended to point people to God, to signal the presence of God with His people. Who but God has authority over nature, disease, death and evil? A carpenter from Nazareth calming a raging storm, giving sight to the blind, calling Lazarus from the tomb, and driving out demonic spirits, emphatically demonstrates that He is the Son of God.
Here was the kingdom of God breaking into our lives. Here the Lord showed His heart for the needy. The miracles of Christ also point to a future when peace, health, and goodness will reign.
JOHN 2:11 – 11 This beginning of miracles did Jesus in Cana of Galilee, and manifested forth his glory; and his disciples believed on him.
