God states in His Word that when we give back to Him what is rightfully His, He will bestow upon us blessings to the point where we are unable to receive any more.
“Bring ye all the tithes into the storehouse, that there may be meat in mine house, and prove me now herewith, saith the LORD of hosts, if I will not open you the windows of heaven, and pour you out a blessing, that there shall not be room enough to receive it.”
