Altogether the New Testament records 37 miracles performed by Jesus. Only one is mentioned in all four gospels, i.e., Matthew, Mark, Luke and John, and that is the feeding of the 5,000. Bear in mind that the number given was for men only (John 6:10), but in addition to them there would have been women and children.
Jesus challenged Philip with the words, “Where shall we buy bread, that these may eat?” (John 6:5) Philip was bewildered, saying, 200 hundred denarii wouldn’t be sufficient to buy bread for them. Andrew found a lad who had 5 barley loaves and 2 small fish. This didn’t perturb Jesus whatsoever, because He knew that He would give thanks for the morsels and multiply them to feed all who were there! When everyone was filled He ordered the disciples to gather fragments of the barley loaves that remained, which turned out to be 12 baskets full. (John 6:8-14)
In a way, this miracle was a proof illustration of Jesus’ claim that He is the bread of life, and that whoever comes believing in Him shall never hunger or thirst. Here are His words, “I am the bread of life. He who comes to Me shall never hunger, and he who believes in Me shall never thirst. (John 6:35)
Every single miracle performed by Jesus met specific needs, and there were witnesses vouching for their authenticity. All of them confirmed the authority of Jesus to forgive sin. Perhaps the most noticeable in this respect was the healing of the paralytic. (Matthew 9:1-8; Mark 2:1-12; Luke 5:17-26) With the paralytic set before Him, the first thing Jesus said was, “Son, be of good cheer; your sins are forgiven you.” (Matthew 9:2)
For saying these words the Scribes accused Him of blasphemy (v 3), He replied to them, “For which is easier, to say, ‘Your sins are forgiven you,’ or to say, ‘Arise and walk?’ But that you may know that the Son of Man has power on earth to forgive sins.” Jesus addressed the paralytic saying, “Arise, take up your bed, and go to your house.” He arose and departed to his house. (Matthew 9:1-8)
Indeed, all of the miracles of Jesus substantiated that He was who He claimed to be, the Son of Man, and that He had the power to forgive sins.
The very first miracle recorded was the occasion when Jesus turned water into wine. (John 2:1-11) This ‘sign’(sēmeion) miracle was a picture of Himself, ‘the good wine’ who came to transform and save people from their sins. (v 10) So this miracle was a figurative representation of Himself.
Another type of miracle demonstrates the ‘power’ (dunamis) of Jesus; for example, the calming of the storm on the Lake. (Matthew 8:23-27; Mark 4:35-41; Luke 8:22-25) Jesus and His disciples were in a boat when ‘a great tempest arose’ causing the boat to be swamped with the seas. (Matthew 8:24) He stood up and rebuked the winds and the sea, and there was a great calm. (Matthew 8:26)
Perhaps the miracle that best demonstrates Jesus’ power to raise the dead, is the raising of Lazarus, which is only recorded in the Gospel of John. (11:1-45) Lazarus was well and truly dead; in fact, he stank (v 39). Jesus commanded Lazarus to “come forth” from the tomb, and he ‘came out bound hand and foot with grave-clothes, and his face was wrapped with a cloth. Jesus said to those present, “Loose him, and let him go.” (vs 43, 44)
So the miracles of Jesus authenticate His power to forgive sins and to raise the dead. By them, He demonstrates that He is the resurrection and the life, and whoever believes in Him shall never die. (vs 25, 26)
