I am coming soon. Hold fast to what you have, so that no one will take your crown. — Revelation 3:11

This isn't salvation by works — it's a warning to persevere. The crown is a gift, but it's given to those who endure. Work out your salvation with fear and trembling, for it's God who works in you. The one who endures to the end will be saved. Hold fast because He's holding you.
