John 6:21

Willingly. Gr. thelo, “to will,” “to desire.” The form of the verb used here may be translated “they began to desire.” This verb emphasizes the change of attitude that came over the disciples on hearing Jesus’ words. Before, they were afraid; now they not only were willing to receive Him, but desired His presence. “They were glad to take him into the boat” (RSV).

Immediately ... at the land. This may be interpreted as a further miracle, indicating that as soon as Jesus entered the ship it was supernaturally transported to the shore. On the other hand, John’s words may be understood as indicating that the storm had driven the boat close to the western shore of the sea by the time Jesus appeared. This appears to be supported by the fact that Matthew and Mark give no indication that the voyage was anything but normal, once Jesus had entered the ship. Matthew’s statement that the disciples were “in the midst of the sea” (Matt. 14:24) when they saw Jesus would be understood then as meaning, not that they were in the geographical center of the lake, but that water was all about them. See on v. 17.
