The first one. Although I would change the saying of. A person has to grab the life jacket, to the fact they guy has to realise he is in danger of dieing, and that God does not throw a lifejacket, He comes and takes you by the hand and pulls you out.. But you have to raise you hand (in humility)
The second one pictures God in a bad light, because there were billions of people at the bttom of the ocean, And God only saved son, and the others, he never even gave a chance.
For a God who claims he is a god of pure love. his actions would not back those claims up. It would more back the claims of his adversary satan, WHo claims God is not a God of love, he just does what he wants,
