All these people were still living by faith when they died. They did not receive the things promised; they only saw them and welcomed them from a distance. And they admitted that they were aliens and strangers on earth.
1 Corinthians 9:14
In the same way, the Lord has commanded that those who preach the gospel should receive their living from the gospel.
Luke 9:25
What good is it for a man to gain the whole world, and yet lose or forfeit his very self?
