George Jeffreys (28 February 1889–26 January 1962) was one of greatest evangelists of the 20th Century, and who had a powerful healing ministry that spread across the United Kingdom. In his book Healing Rays, Jeffreys attempted to provide an explanation for the purpose of miracles and healings.
It is evident to the careful reader of the Gospels that miracles and healings served more than one purpose. They were not only given to attest the ministry of our Lord and those He had appointed, but they were instrumental in attracting people to Christ and in encouraging faith. Let us take some instances in the Gospel of John. In chapter 2, verse 11, we read, “This beginning of miracles did Jesus in Cana of galilee, and manifested forth His glory; and His disciples believe on Him”. In verse 23 of the same chapter we read, “Now when He was in Jerusalem at the Passover, in the feast day, many believed in His name, when they saw the miracles which He did”. Nicodemus, in chapter 3, referred to our Lord’s miracles and the inference is that they were partly the means of bringing him to Christ. In chapter 6, verse 2, we are told, “And a great multitude followed Him, because they saw His miracles which He did on them that were diseased”. It was the miracles of the loaves and fishes that drew forth the following testimony from those who stood near, “This is of a truth that prophet that should come into the world”. It was the miracles that made people conclude that Jesus was the Christ, for they said, in chapter 7, verse 31, “When Christ cometh, will He do more miracles that these which this Man hath done?” In chapter 11, verse 45, we read of many Jews believing, after seeing the things which Jesus did. It was the miracle of the raising of Lazarus from the dead that made the Jews of chapter 12, verse 11, believe on Jesus, and again it was the miracle that brought more people into contact with Him according to the 18th verse.
