1 Corinthians 3:5-15 KJV
5 Who then is Paul, and who is Apollos, but ministers by whom ye believed, even as the Lord gave to every man? 6 I have planted, Apollos watered; but God gave the increase.7 So then neither is he that planteth any thing, neither he that watereth; but God that giveth the increase.8 Now he that planteth and he that watereth are one: and every man shall receive his own reward according to his own labour.9 For we are labourers together with God: ye are God's husbandry, ye are God's building.10 According to the grace of God which is given unto me, as a wise masterbuilder, I have laid the foundation, and another buildeth thereon. But let every man take heed how he buildeth thereupon.11 For other foundation can no man lay than that is laid, which is Jesus Christ.12 Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble; 13 Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is.14 If any man's work abide which he hath built thereupon, he shall receive a reward.15 If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.
1 Corinthians 3:18-19 KJV
18 Let no man deceive himself. If any man among you seemeth to be wise in this world, let him become a fool, that he may be wise.19 For the wisdom of this world is foolishness with God. For it is written, He taketh the wise in their own craftiness.
2 Corinthians 3:3 KJV
3 Forasmuch as ye are manifestly declared to be the epistle of Christ ministered by us, written not with ink, but with the Spirit of the living God; not in tables of stone, but in fleshy tables of the heart.
Matthew 9:37-38 KJV
37 Then saith he unto his disciples, The harvest truly is plenteous, but the labourers are few; 38 Pray ye therefore the Lord of the harvest, that he will send forth labourers into his harvest.
John 4:34-38 KJV
34 Jesus saith unto them, My meat is to do the will of him that sent me, and to finish his work.35 Say not ye, There are yet four months, and then cometh harvest? behold, I say unto you, Lift up your eyes, and look on the fields; for they are white already to harvest.36 And he that reapeth receiveth wages, and gathereth fruit unto life eternal: that both he that soweth and he that reapeth may rejoice together.37 And herein is that saying true, One soweth, and another reapeth.38 I sent you to reap that whereon ye bestowed no labour: other men laboured, and ye are entered into their labours.
1 Corinthians 15:58 KJV
58 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.
