Therefore, my brothers, whom I love and long for, my joy and crown, that is how you must stand firm in the Lord, my beloved. — Philippians 4:1

Paul urges us to stand fast in the Lord. The Lord loves justice and doesn't forsake His saints — they are preserved forever. The one who endures to the end will be saved, not because of human resolve, but because the Lord preserves your going out and your coming in. Hold fast what you have, that no one may take your crown. You stand by faith, and it's God who holds you standing.
