It was obvious from the miracles Jesus performed that he had supernatural ability to do things that no one had ever seen done before. What was less obvious, but just as true, was that Jesus’ disciples had the same supernatural ability. When Jesus was about to send his disciples out to preach the gospel, it says in Luke 9:1, “Then he called his twelve disciples together, and gave them power and authority over all devils, and to cure diseases.” The Greek word translated power, dunamis (doo’-nam-is) specifically refers to miraculous power (1411), but the Greek word dunamis is derived from, dunamai (doo’-nam-ahee) suggests that the twelve apostles had limitless power, the ability to do everything that Jesus was able to. An example of this is found in Matthew’s gospel where it is recorded that Peter walked on the Sea of Galilee (Matthew 14:29). After Peter was come down out of the ship, Matthew said, “he walked on the water, to go to Jesus. But when he saw the wind boisterous, he was afraid; and beginning to sink, he cried, saying, Lord, save me” (Matthew 14:29-30). Jesus reached out and grabbed Peter by the hand in order to keep him from sinking, and then rebuked him stating, “O thou of little faith, wherefore didst thou doubt” (Matthew 14:31).

The problem with Peter’s faith was that it lacked confidence. The term Jesus used to describe it, “little faith” could also be translated “puny argument” (3641/3982). In other words, Peter’s demonstration of his faith was unconvincing. Even though he got out of the boat, Peter wasn’t certain he wanted to walk across the sea as Jesus had just done (Matthew 14:25). Jesus pointed out that the reason Peter began to sink was because he doubted (Matthew 14:31) or mentally wavered from his original conviction (1365) about the possibility that he could do what Jesus had commanded him to, “come” to him on the water (Matthew 14:29). Matthew said the cause of Peter’s mental wavering was fear. He explained, “But when he saw the wind boisterous, he was afraid” (Matthew 14:30). Although Peter may have been overcome by fear, it was not his fear that caused him to doubt. The Greek word translated doubt, distazo (dis-tad’-zo) means to duplicate (1365), the word distazo is derived from, dis (dece) which means twice (1364) or duo (doo’-o) to have two of something. At the moment when he began to doubt, it is likely that Peter thought twice about what he was doing and realized that walking on water was humanly impossible; but what is even more likely than that, is that at the moment his doubt got the better of him, Peter realized that he and Jesus were doing the same thing and that meant that, if Peter continued, he would no longer be able to excuse himself from doing whatever God commanded him to.
