Whereunto I also labour, striving according to his working, which worketh in me mightily.

Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labour is not in vain in the Lord.

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.

And let us not be weary in well doing: for in due season we shall reap, if we faint not.
