'Reward' in the Bible

He who plants and he who waters are one [in importance and esteem, working toward the same purpose]; but each will receive his own reward according to his own labor.

If any person’s work which he has built [on this foundation, that is, any outcome of his effort] remains [and survives this test], he will receive a reward.

But if any person’s work is burned up [by the test], he will suffer the loss [of his reward]; yet he himself will be saved, but only as [one who has barely escaped] through fire.

For if I do this work of my own free will, then I have a reward; but if it is not of my will [but by God’s choosing], I have been entrusted with a [sacred] stewardship.

What then is my reward? [Just this:] that, when I preach the gospel, I may offer the gospel without charge [to everyone], so as not to take advantage of my rights [as a preacher and apostle] in [preaching] the gospel.
