1 Corinthians 4:12; 1 Corinthians 15:10; 1 Corinthians 16:16

12 And labour , working with our own hands: being reviled , we bless ; being persecuted , we suffer it :
10 But by the grace of God I am what I am : and his grace which was bestowed upon me was not in vain; but I laboured more abundantly than they all: yet not I, but the grace of God which was with me.
16 That ye submit yourselves unto such, and to every one that helpeth with us, and laboureth .
