Romans 14:5-8

One person thinks that one day is more important than another. And someone else thinks that every day is the same. Each one should be sure in his own mind. The person who thinks one day is more important than other days is doing that for the Lord. And the one who eats all kinds of food is doing that for the Lord. Yes, he gives thanks to God for that food. And the man who refuses to eat some foods does that for the Lord, and he gives thanks to God. For we do not live or die for ourselves. If we live, we are living for the Lord. And if we die, we are dying for the Lord. So living or dying, we belong to the Lord.
