In Christian stewardship which states that everything we have comes as a gift from God and we are simply stewards who manage the affairs of God on earth. The biblical mandate of tithing which has its roots in the Old Testament is a critical part of the believers’ life.

Malachi 3:6-12
"I the LORD do not change. So you, O descendants of Jacob, are not destroyed. Ever since the time of your forefathers you have turned away from my decrees and have not kept them. Return to me, and I will return to you," says the LORD Almighty. "But you ask, 'How are we to return?' "Will a man rob God? Yet you rob me. "But you ask, 'How do we rob you?' "In tithes and offerings. 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," says the LORD Almighty, "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. I will prevent pests from devouring your crops, and the vines in your fields will not cast their fruit," says the LORD Almighty. "Then all the nations will call you blessed, for yours will be a delightful land," says the LORD Almighty.
