Why are you here on earth? Why do you exist? … This is a big question, of course, not the sort of question that can be fully answered in a few words. But it is worth noting that Ephesians 1:12 answers the “Why do you exist?” question clearly and succinctly: “for the praise of his glory.” There it is. You exist for the praise of God’s glory. That’s why you’re here on earth.
