I do not want to sound too difficult, but the text never says that Jesus walked on the water. I owe this observation to a pastor friend of mine, the Rev. Dr. Kevin Golden.
In both accounts, in Matthew 14 and in Mark 6, the text says that Jesus walked on the sea. There is a significant difference.
The sea is something that is often connected to God. The Old Testament text for this Sunday is from the book of Job (38:8), where the Lord asks, 'Who shut in the sea with doors...? Obviously Job did not. We were certainly not there. And Peter was not there either.
In Revelation 21:1 the text says that 'the sea was no more'. Imagine a time of no storms, no troubles. Imagine never feeling like you are drowning with all the things that need to be done. That time is coming.
Peter wanted to come to Jesus on the water, not the sea. Again, there is a significant difference. Again, that is probably why he started to drown.
The Son of God was there when the sea was shut in. He will be there when the sea will be no more. He continues to be in complete control of the situation.
This text is not about Peter. This text is also not about someone walking on the water OR the sea! This text is about Jesus, the one who will save his people from their sins.
It is nice to hear about what Jesus did one day. But it is even nicer to hear about what he did one day for you.
