Romans 14:5-10

One person prefers one day over another day, and another person regards every day alike. Each one must be fully convinced in his own mind. The one who is intent on the day is intent on it for the Lord, and the one who eats eats for the Lord, because he is thankful to God, and the one who does not eat does not eat for the Lord, and he is thankful to God. For none of us lives for himself and none dies for himself. For if we live, we live for the Lord, and if we die, we die for the Lord. Therefore whether we live or whether we die, we are the Lord’s. For Christ died and became alive again for this reason, in order that he might be Lord of both the dead and the living. But why do you judge your brother? Or also, why do you despise your brother? For we will all stand before the judgment seat of God.
