Give All You Can

"O that God would enable me once more, before I go hence and am no more seen, to lift up my voice like a trumpet to those who gain and save all they can, but do not give all they can! ...Many of your brethren, beloved of God, have not food to eat; they have not raiment to put on; they have not a place where to lay their head. And why are they thus distressed? Because you impiously, unjustly, and cruelly detain from them what your Master and theirs lodges in your hands on purpose to supply their wants! ...In the name of God, what are you doing?"

John Wesley, Sermon 116

Wesley does not mince words - he firmly believes that money is meant to care for our needs, not our desires. We are to provide the same for our household. And the rest is to be given away.

We'll let him speak for himself. Here follows an abridged version of Sermon 50, Section III, on giving all you can. Abridgements are not marked with ellipses; I do not believe they change the sense. The full sermon is available here.

1. But let not any man imagine that he has done anything, barely by going thus far, by "gaining and saving all he can," if he were to stop here. Having, First, gained all you can, and, Secondly saved all you can, Then "give all you can."
2. In order to see the ground and reason of this, consider, when the Possessor of heaven and earth brought you into being, and placed you in this world, he placed you here not as a proprietor, but a steward: As such he entrusted you, for a season, with goods of various kinds; but the sole property of these still rests in him. And he has told you, in the most clear and express terms, how you are to employ [them] for him, in such a manner, that it may be all an holy sacrifice, acceptable through Christ Jesus.
3. If you desire to be a faithful and a wise steward, out of that portion of your Lord's goods which he has for the present lodged in your hands, First, provide things needful for yourself; food to eat, raiment to put on, whatever nature moderately requires for preserving the body in health and strength. Secondly, provide these for your household. If when this is done there be an overplus left, then "do good to them that are of the household of faith." If there be an overplus still, "as you have opportunity, do good unto all men." In so doing, you give all you can; nay, in a sound sense, all you have: For all that is laid out in this manner is really given to God.
4. If, then, a doubt should at any time arise in your mind concerning what you are going to expend, you have an easy way to remove it. Calmly and seriously inquire, "(1.) Am I acting herein, not as a proprietor, but as a steward of my Lord's goods? (2.) Am I doing this in obedience to his Word? (3.) Can I offer up this action, this expense, as a sacrifice to God through Jesus Christ? (4.) Have I reason to believe that for this very work I shall have a reward at the resurrection of the just?" You will seldom need anything more to remove any doubt which arises on this head.
5. If any doubt still remain, you may farther examine yourself by prayer according to those heads of inquiry. Try whether you can say to the Searcher of hearts, your conscience not condemning you, "Lord, thou seest I am going to expend this sum on that food, apparel, furniture. And thou knowest, I act herein with a single eye as a steward of thy goods, expending this portion of them thus in pursuance of the design thou hadst in entrusting me with them. Thou knowest I do this in obedience to the Lord, as thou commandest, and because thou commandest it. Let this, I beseech thee, be an holy sacrifice, acceptable through Jesus Christ! And give me a witness in myself that for this labour of love I shall have a recompense when thou rewardest every man according to his works." Now if your conscience bear you witness in the Holy Ghost that this prayer is well-pleasing to God, then have you no reason to doubt but that expense is right and good, and such as will never make you ashamed.
6. You see the nature and extent of truly Christian prudence so far as it relates to the use of that great talent, money. Gain all you can, without hurting either yourself or your neighbour, in soul or body; -- save all you can, by cutting off every expense which serves only to indulge foolish desire;  -- and then, give all you can, or, in other words, give all you have to God. "Render unto God," not a tenth, not a third, not half, but all that is God's, be it more or less; by employing all on yourself, your household, the household of faith, and all mankind, in such a manner, that you may give a good account of your stewardship when ye can be no longer stewards.

What do you think?
Wesley claims that we should treat all of "our" money - not some percentage - as God's, not our own. Do you agree with him? What do you think of his fourfold test in paragraph 4 on how to spend God's money?
