and if Christ hath not been raised, then is our preaching vain, your faith also is vain.

by which also ye are saved, if ye hold fast the word which I preached unto you, except ye believed in vain.

Which things also we speak, not in words which man's wisdom teacheth, but which the Spirit teacheth; combining spiritual things with spiritual words .

howbeit in the church I had rather speak five words with my understanding, that I might instruct others also, than ten thousand words in a tongue.

and again, The Lord knoweth the reasonings of the wise that they are vain.

But by the grace of God I am what I am: and his grace which was bestowed upon me was not found vain; but I labored more abundantly than they all: yet not I, but the grace of God which was with me.

and if Christ hath not been raised, your faith is vain; ye are yet in your sins.

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