The Bible says in Malachi 3:8 and 10 , “Begin by being honest. Do honest people rob God? But you rob me day after day. “You ask, “How have we robbed you?’ “The tithe and the offering – that’s how! Bring your full tithe to the Temple treasury so there will be ample provisions in my Temple. Test me in this and see if I don’t open up heaven itself to you and pour out blessings beyond your wildest dreams…”
The seriousness of giving is seen here--giving is a command of God.
This Scripture also promises that God will “throw open the floodgates of heaven and pour out so much blessing that you will not have room enough for it” if we honor God in our giving!
God commands us not to test Him in any area, except in this area of giving. He says, ‘Test me…try it…let me prove it to you.’ God stands by this promise—if we obey Him financially, we will be blessed financially.
