Give and it will be given to you. A good measure, pressed down, shaken together, running over, will be put into your lap; for the measure you give will be the measure you get back. Luke 6:38.
God is watching our every move, He reads our thoughts and intentions and hears our frustrations. He is in us via His Spirit with which we were created when we were conceived in our mother's womb. Think of a microchip, Intel, inside a computer. We are made with a God-chip that tracts us and monitors us. God watches everyone from the inside out.
He watches us when we are generous and when we are selfish. He watches us give and He watches us steal.
When we are generous, we are being vehicles of God who is giving to others through us. God is as much the source of prosperity as He is the source of the abundance in His creation, earth. Let God use you.
Give your time, your love, your possessions and your money, all that you have, and all that you are, give it away. God sees you reduce yourself and fills you up again bigger than before, so you can give more.
The principle that giving is as a fountain that never empties is as axiomatic as the principles of entropy, of gravitation or of magnetism. The elements of a principal always result in the effects of the principle.
Be like God; bless people. Blessing others unites heaven with earth.
