Yes indeed death comes mysterious. Nobody knows except gods and angels who take life. But angels are like executors. All control belongs to God. Everything we experience is the best gift by God, even though sometimes we like and dislike. Because what you think is good is not necessarily good according to God. Because God has planned the best things for us that we cannot expect. Our brains will not be able to, so God sends down the book as a guide for us. So try to be good at God, hopefully useful
