Money has a law and it is the law of giving. "Give and it shall be giving unto you; good measure, pressed down, and shaken together, shall men give into your bossom".
You do not 'have' to 'give' instead you 'give' to 'have'. Many at times we do not give because we feel, we do not have but but the secret of having is giving, give out of the little you have.
It is giving that empowers your wealth. It is what you sow that you will reap -Gal.6:7. What are you sowing now? The bible says, while the earth remains, seed time and harvest,..... shall not cease- (Gen 8:22)
There is always a reaping time for every farmer who sows. A farmer who did not sow during the planting season should not expect to reap during the harvest season. When a farmer eats all his produce, he will have nothing to sow, and nothing to reap. Thing might be difficult at some point in time, but you have to learn and find a way of giving.
Know that whatsoever you give unto man, you are also giving unto God
