Romans 14:7 WEB

⁵  One man esteems one day as more important. Another esteems every day alike. Let each man be fully assured in his own mind.

⁶  He who observes the day, observes it to the Lord; and he who does not observe the day, to the Lord he does not observe it. He who eats, eats to the Lord, for he gives God thanks. He who doesn't eat, to the Lord he doesn't eat, and gives God thanks.

⁷  For none of us lives to himself, and none dies to himself.

⁸  For if we live, we live to the Lord. Or if we die, we die to the Lord. If therefore we live or die, we are the Lord's.

⁹  For to this end Christ died, rose, and lived again, that he might be Lord of both the dead and the living.
