I think this song is about having cold feet and dealing with the lifestyle changes that come with getting married.
Verse 1 he is nervous and about to walk down the isle. I think he relates walking down the isle to "walking on water" (trying to be perfect)
Verse 2 - still nervous, wanting to stop the wedding - "wishing you could stop it"
Verse 3 - things aren't going to be any different if he keeps on going the direction he is going, and he realizes its time for a change, but is still apprehensive.
