'Doing' in the Bible

But if you do marry, you have not sinned [in doing so]; and if a virgin marries, she has not sinned [in doing so]. Yet those [who marry] will have troubles (special challenges) in this life, and I am trying to spare you that.

But the man who stands firmly committed in his heart, having no compulsion [to yield to his daughter’s request], and has authority over his own will, and has decided in his own heart to keep his own virgin [daughter from being married], he will do well.

Or is it only Barnabas and I who have no right to stop doing manual labor [in order to support our ministry]?

Therefore, my beloved brothers and sisters, be steadfast, immovable, always excelling in the work of the Lord [always doing your best and doing more than is needed], being continually aware that your labor [even to the point of exhaustion] in the Lord is not futile nor wasted [it is never without purpose].

If Timothy comes, see to it that [you put him at ease, so that] he has nothing to fear in regard to you, for he is [devotedly] doing the Lord’s work, just as I am.
