Does God really protect us?

Do you think those eighteen people who died when the tower in Siloam fell were more guilty than all the others living in Jerusalem? I tell you, no! But unless you repent, you too will all perish just as they will. (Luke 13:4–5)
There are times when we experience God protecting us from danger, but there are also times when He does not. We cannot fully understand why God prevents certain dangers while allowing others to occur.
In this world, everyone faces death through accidents, war, and disease. We cannot conclude that a sudden death occurred because that person had more sins.
The conclusion of faith is not a life of living comfortably and being protected on this earth, but rather believing in Jesus Christ—who became the sacrificial lamb in place of our sins and rose from the dead—repenting, and hoping for salvation after death.
