There is a sore evil which I have seen under the sun, namely, riches kept for the owners thereof to their hurt. Ecclesiastes 5:13 KJV
God so loved He gave. God is generous by nature. Godliness requires that the Christian be generous as his Creator.
God is also a Rewarder of those who diligently seek and follow Him. That’s why the promise of return we see in Luke 6:
Give, and it shall be given unto you; good measure, pressed down, and shaken together, and running over, shall men give into your bosom. For with the same measure that ye mete withal it shall be measured to you again. Luke 6:38 KJV
