Return to God what belongs to Him and He will return a blessing to you. It is not too late. Listen to what He says: “You are under a curse—the whole nation of you—because you are robbing me. Bring the whole tithe into the storehouse, that there may be food in my house. Test me in this and see if I will not throw open the floodgates of heaven and pour out so much blessing that you will not have room enough for it. Then all the nations will call you blessed, for yours will be a delightful land,” says the Lord Almighty. A blessed nation is a nation that acts on its faith in Almighty God. God doesn’t desire mere lip service; He wants the real deal. Even though we cannot fully see or comprehend Him now, there is nothing more real than God. How we obey His Word is a reflection of our values and it has always been that way.
This warning about robbing God reminds me of a story that did not end well for a king in New Testament times. Herod the Great’s grandson was the new leader on the throne and he caused much trouble for the early church. Although I do not know of his tithing practices, King Herod robbed God of the praise and glory due Him and was immediately eaten by worms and then he died. There may be a number of reasons that motivate us to give to God. I love giving back to Him because all good blessings come from Him.
