ANSWER: Systematic giving is very desirable. Some could give more than a tenth, and some less. This matter is left by Christ as a voluntary exercise of our benevolent sensibilities. In the Acts, where we look for an application of Christ's precepts, we find no requirement of the tithe. When Paul raised money for the poor, though educated as a Pharisee, he said nothing about the tithe, but "let each one of you lay by him in store, as he may prosper." Christianity is a bundle of principles rather than a code of minute rules. This is what makes the Gospel the law of liberty and not servility.
