"I would say that one of the best things that could happen to many believers would be for them to be led to give away, all at one time, a substantial part of their savings. That is, they should give a substantial part of their capital. Why? Because there is something about giving away a sizable percentage of one’s money – and, of course, the amount would vary entirely from one individual to another – that is spiritually invigorating. And there is seldom a case in which a large gift does not throw the Christian back on the Lord and increase the feeling that he is all-wonderful and that he is more than able to care for the one who trusts him. I have seen this happen in many instances. And I have never known a true Christian to be sorry for even the most sacrificial giving afterward."
