Romans 14:7-9

7 None of us lives for himself [for his own benefit, but for the Lord], and none of us dies for himself [but for the Lord]. 8 If we live, we live for the Lord, and if we die, we die for the Lord. So then, whether we live or die, we are the Lord’s. 9 For Christ died and lived again for this reason, that He might be Lord of both the dead and the living.
