A couple of more thoughts on giving: Giving in the NT is not limited to those who preach the gospel only. Paul teaches many times to give one to another. James mentions it as well. If you are ONLY giving to one man, you are not truly giving.
James 2:2-3 "If a brother or sister be naked, and destitute of daily food, and one of you say unto them, Depart in peace, be ye warmed and filled; notwithstanding ye give them not those things which are needful to the body; what doth it profit?"
Paul spends a whole chapter in
II Cor. 9 speaking about giving to the SAINTS.
1 For as touching the ministering to the saints, it is superfluous for me to write to you:
and says this:
6 But this I say, He which soweth sparingly shall reap also sparingly; and he which soweth bountifully shall reap also bountifully.
7 Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver.
And remember... Paul here is NOT talking about giving to himself, or the ministry, but the SAINTS! Helping each other out...
12 For the administration of this service not only supplieth the want of the saints, but is abundant also by many thanksgivings unto God;
Remember, God blesses giving, no matter how little or much. But Paul certainly taught to give according as the LORD has blessed you,
AND to be sure to take care of your brothers and sisters too.
