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.

not meaning the immoral people of this world, or the greedy ones and swindlers, or idolaters, for then you would have to get out of the world and human society altogether!

Do you not know that those who officiate in the sacred services of the temple eat from the temple [offerings of meat and bread] and those who regularly attend the altar have their share from the [offerings brought to the] altar?

So also [on the same principle] the Lord directed those who preach the gospel to get their living from the gospel.

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.

for when you eat, each one hurries to get his own supper first [not waiting for others or the poor]. So one goes hungry while another gets drunk.
