Jonah chapter 2

After reading chapter 2:

*This whole chapter is a poetic prayer that Jonah prays to Yahweh, while inside a fish, without breathable air. The odd thing about this poem is it is written in the past tense. So, he's hanging out in the fish and he thanks God for saving him from a certain death in the ocean. Supposedly, as he was about to drown, he "remembered" Yahweh and he prayed. God saved him. Now he is safe inside the fish. (If you were inside a fish would you feel safe?), Now he will make sacrifices and keep his vows. Did he not believe Yahweh had any power before this? I would think if someone actually believed in a powerful god that could punish them, they would be mighty cautious not to irritate that god to begin with.

*Yahweh told the fish to spit up Jonah, and it did. Not only that, it conveniently spit Jonah on to dry land. After a three day belly ache, it just swam up to the beach and retched Jonah out. What's not to believe?
