Romans 14:6-7

"He that regardeth the day, regardeth it unto the Lord; and he that regardeth not the day, to the Lord he doth not regard it. He that eateth, eateth to the Lord, for he giveth God thanks; and he that eateth not, to the Lord he eateth not, and giveth God thanks. For none of us liveth to himself, and no man dieth to himself" - Romans 14:6-7 KJV
