The Bible teaches that “until death do us part” isn’t just a traditional ending to a ceremony, but a boundary line drawn by God. In a Christian marriage, the vow of permanence creates a “death-bound” commitment that only ends when one spouse enters eternity. This finality is actually what gives marriage its beauty; it provides a secure, lifelong container where two people can grow, change, and fail without the fear of being abandoned before the journey is over.
