The Mariner's spiritual rebirth begins when he falls asleep. This occurs in Part V, in the first stanza. He describes being wet and tired, but feeling awake, and lighter than he was before. He also mentions Mary, who is a spiritual figure herself, which shows the reader that this is the beginning of a spiritual moment in the poem.
This isn't neccessarily true. Your introduction can still make sense without the hook, and the information inside the introduction part should really not directly depend on the hook to explain them, they should either be self explanatory, or you should explain them there.
Hopefully this helps!
