Was Jesus' entire earthly ministry marked by miracles?
Yes, His entire earthly ministry was marked by miracles. From the start of His ministry through the three years of His earthly sojourn in Israel, He performed miracle after miracle, and John the Baptist heard in prison of the works of Christ.
Les explains that the sign gifts begin with Jesus' earthly ministry. He notes that Jesus began His ministry with miracles, and all through the three years of His earthly sojourn in Israel He performed miracle after miracle. In Matthew 11:2, John the Baptist, while in prison, heard of the works of Christ and sent two of his disciples to ask Jesus whether He was the One who should come or whether they should look for another. Even John, whose birth was miraculous, questioned from prison, knowing Jesus had power to take him out of the authorities' hands but was not doing it.
