So this is just another problem of evil question, but it’s been bothering me for awhile

Sometimes God uses disasters to bring people to himself. Maggie’s wasn’t a natural disaster, but a personal one. And God used a natural event, potentially disastrous, to ‘catch’ John Newton, the author of “Amazing Grace”. He was a slaver, a slaving ship captain, and the ship was caught in a severe storm and about to sink.
