Rom 14:1 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.

Rom 14:19 Let us therefore follow after the things which make for peace, and things wherewith one may edify another. 20 For meat destroy not the work of God. All things indeed are pure; but it is evil for that man who eateth with offence. 21 It is good neither to eat flesh, nor to drink wine, nor any thing whereby thy brother stumbleth, or is offended, or is made weak.

1 Cor 1:26 For ye see your calling, brethren, how that not many wise men after the flesh, not many mighty, not many noble, are called: 27 But God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty;

2 Cor 12:9 And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me. 10 Therefore I take pleasure in infirmities, in reproaches, in necessities, in persecutions, in distresses for Christ's sake: for when I am weak, then am I strong.
