Romans 14:6-8

Those who think one day is more important than other days are doing that for the Lord. And those who eat all kinds of food are doing that for the Lord, and they give thanks to God. Others who refuse to eat some foods do that for the Lord, and they give thanks to God. 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.
