I have every reason to believe, that, had I begun to lay up, the Lord would have stopped the supplies, and thus, the ability of doing so was only _apparent._ Let no one profess to trust in God, and yet lay up for future wants, otherwise the Lord will first send him to the hoard he has amassed, before He can answer the prayer for more.
"There is that scattereth, and yet increaseth; and there is that withholdeth _more than is meet,_ but it tendeth to poverty." (Prov. xi. 24.) Notice here the word _"more than is meet;"_ it is not said, withholdeth all; but "more than is meet" viz., while he gives, it is so little, in comparison with what it might be, and ought to be, that it tendeth to poverty.
Believers should seek more and more to enter into the grace and love of God, in giving His only-begotten Son, and into the grace and love of the Lord Jesus, in giving Himself in our room, in order that, constrained by love and gratitude, they may be increasingly led to surrender their bodily and mental strength, their time, gifts, talents, property, position in life, rank, and all they have and are to the Lord. By this I do not mean that they should give up their business, trade, or profession, and become preachers; nor do I mean that they should take all their money and give it to the first beggar who asks for it; but that they should hold all they have and are, for the Lord, not as owners, but as stewards, and be willing, _at His bidding,_ to use for Him part or all they have. However short the believer may fall, nothing less than this should be his aim.
