When the disciples are battered by the waves at sea, JesusJesus is the Messiah whose life, death, and resurrection are God's saving act for humanity More comes to them walking on the water and calms their fear with his assuring word, “It is I.” At the Lord’s command PeterThe disciple who denied Jesus during his trial but later became a leader in proclaiming Jesus More also walks on the water, but in fear begins to sink. Jesus reaches out his hand in rescue, but reproves his little faith.
This second story of the disciples at sea (see 8:23-27) is not so much a miracle as it is a story of faith. It is replete with Matthean motifs, including for the first time Peter’s emerging role as a representative of the disciples and thereby of the believing community. The “immediately” of its opening verse pointedly joins it to the preceding story of the feeding of the five thousand, and in Matthew’s telling it becomes essentially a parableA parable is a brief story with a setting, an action, and a result. A prominent aspect of Jesus' teaching was telling parables to illustrate something about the kingdom, or reign, of God. More of faith. The disciples are at risk on the sea without their master who is alone in prayer. Finally, near morning, Jesus comes to them walking on the water, but in their fear they fail to recognize him. Jesus’ command for them to stop being afraid contains within it the revelatory “I Am.” Peter responds with words of faith, “Lord, if it is you, command me to come to you on the water.” At Jesus’ command to come, Peter indeed does walk on the water, but when he takes his eyes off Jesus, he begins to sink and cries out to the Lord for rescue. Jesus reaches out, takes him by hand, and catches him up, and then chastises him for his “little faith.”
Twice Peter has addressed Jesus with words of faith, calling him “Lord.” Trusting in Jesus’ command to “Come!” he has walked on the water. When in peril he cries out to Jesus as “Savior,” and even in the midst of his doubting he is rescued. Though Jesus chides Peter for his “little faith” (a word that is essentially unique to Matthew’s gospel narrative), still, at the Lord’s touch, the wind ceases and the boat with the disciples is safe. All those in the boat respond in the only way appropriate for disciples: they worship Jesus as “Truly…the Son of God.” The combined motifs of doubt and worship mirror the reaction of the disciples when they meet the resurrected Lord on the mountain (28:17). This combination and the fact that the word translated “doubt” occurs only in these two places in MatthewA tax collector who became one of Jesus' 12 disciples More emphasize the importance of this story as a parable and model of faith for Matthew’s community.
