I like how John MacArthur speaks about miracles, “A miracle is an extraordinary event wrought by God through human agency, an event that cannot be explained by natural forces. Miracles are always designed to authenticate the human instrument God has chosen to declare a specific revelation to those who witness the miracle.”
Isaiah prophesied that the Messiah would be a miracle worker. Isaiah 29:18 says, “In that day the deaf shall hear the words of a book, and out of their gloom and darkness the eyes of the blind shall see.” He adds in Isaiah 35:4-6, “Say to those who have an anxious heart, ‘Be strong; fear not! Behold, your God will come with vengeance, with the recompense of God. He will come and save you.’ Then the eyes of the blind shall be opened, and the ears of the deaf unstopped; then shall the lame man leap like a deer, and the tongue of the mute sing for joy. For waters break forth in the wilderness, and streams in the desert.”
In Matthew chapter 11, John the Baptist is in prison. In verses 2-3, he has one specific question, “Now when John heard in prison about the deeds of the Christ, he sent word by his disciples and said to him, ‘Are you the one who is to come, or shall we look for another?’” He wanted to know if Jesus was the promised Messiah. Jesus’ answer shows He is the miracle man, “And Jesus answered them, ‘Go and tell John what you hear and see: the blind receive their sight and the lame walk, lepers are cleansed and the deaf hear, and the dead are raised up, and the poor have good news preached to them. And blessed is the one who is not offended by me’” (Matthew 11:4-6). Jesus knew that John the Baptist knew the Messiah would perform miracles. His actions spoke as loud as any words.
Jesus healing someone is recorded about 40 times in Scripture. Matthew 9:30, “And their eyes were opened. And Jesus sternly warned them, ‘See that no one knows about it.’” Matthew 12:22 adds, “Then a demon-oppressed man who was blind and mute was brought to him, and he healed him, so that the man spoke and saw.” Mark 7:37 says, “And they were astonished beyond measure, saying, ‘He has done all things well. He even makes the deaf hear and the mute speak.’” John 9:39 continues the list of healings performed by Jesus, “Jesus said, ‘For judgment I came into this world, that those who do not see may see, and those who see may become blind.’”
One characteristic of the Messiah was that He would perform miracles. Jesus fulfilled that prophecy time and time again.
C.S. Lewis gives another reason Jesus performed miracles, “Miracles are a retelling in small letters of the very same story which is written across the whole world in letters too large for some of us to see.”
God loved us so much that He sent His only son to die for us. The chasm that was created by our sin was bridged by the work of Jesus. His miracles showed His love. His life showed His love. His death showed His love.
