11:18 A wicked man earns deceptive wages, but one who sows righteousness gets a sure reward.

6:3 For if any one thinks he is something, when he is nothing, he deceives himself. 6:4 But let each one test his own work, and then his reason to boast will be in himself alone and not in his neighbor. 6:5 For each man will have to bear his own load. 6:6 Let him who is taught the word share all good things with him who teaches. 6:7 Do not be deceived; God is not mocked, for whatever a man sows, that he will also reap. 6:8 For he who sows to his own flesh will from the flesh reap corruption; but he who sows to the Spirit will from the Spirit reap eternal life.

40:8 The grass withers, the flower fades; but the word of our God will stand for ever.
