The New Testament does not teach a doctrine of tithing (i.e., the mandatory giving of 10 percent of one’s income). Nor does Paul define what constitutes giving generously. He does not even provide a target number or general guidelines. The only rule is to give freely and generously as an expression of our continuing trust in God’s grace (9:5-8). Paul simply assumes that believers will give all they can to meet as many needs as they can in order to glorify God as much as they can.
