The passage in question is from Matthew 14:
24But the ship was now in the midst of the sea, tossed with waves: for the wind was contrary. 25And in the fourth watch of the night Jesus went unto them, walking on the sea.
26And when the disciples saw him walking on the sea, they were troubled, saying, It is a spirit; and they cried out for fear.
27But straightway Jesus spake unto them, saying, Be of good cheer; it is I; be not afraid.
28And Peter answered him and said, Lord, if it be thou, bid me come unto thee on the water.
29And he said, Come. And when Peter was come down out of the ship, he walked on the water, to go to Jesus.
30But when he saw the wind boisterous, he was afraid; and beginning to sink, he cried, saying, Lord, save me.
31And immediately Jesus stretched forth his hand, and caught him, and said unto him, O thou of little faith, wherefore didst thou doubt?
32And when they were come into the ship, the wind ceased.
The point that Goinheix has proposed is that Jesus walked around the water, not on the water.
Scripture clearly says that:
1) the ship was in the midst of the sea;
2) although the ship was in the midst of the sea (v.24), Jesus and the disciples conversed (v.26, 27, 28)
3) Peter asked to come out "on the water" with Jesus (v.28)
4) Peter sank (v.30)
5) Jesus went into (boarded) the ship (which, as we recall from v.24, was in the midst of the sea)
I think it's pretty clear that scripture shows Jesus walked on the water, not around it.
