Romans 14:1-3 (KJV)
1 Him that is weak in the faith receive ye, but not to doubtful disputations.
2 For one believeth that he may eat all things: another, who is weak, eateth herbs.
3 Let not him that eateth despise him that eateth not; and let not him which eateth not judge him that eateth: for God hath received him.
Romans 14:11,12 (KJV)
11 For it is written, As I live, saith the Lord, every knee shall bow to me, and every tongue shall confess to God.
12 So then every one of us shall give account of himself to God.
Romans 14:5,6 (KJV)
5 One man esteemeth one day above another: another esteemeth every day alike . Let every man be fully persuaded in his own mind.
6 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.
