The first of these is a point the most difficult for the depraved heart to reach. Self-interest clamors most loudly for the smallest sum possible. Her whole strength must here be encountered. But selfishness, properly so called, has nothing to do with the question. The rule determining the amount must be fixed upon, not only entirely without her aid, but in direct opposition to her insidious suggestions. It must also be a rule growing out of those principles which take hold of, and bind the conscience; and therefore clearly taught in the Bible. This is a consideration which may not be overlooked. If we endeavor to deduce a rule from principles not found nor recognized in the Scriptures, the influence will be disastrous; we shall rather strengthen, than weaken, the covetous tendencies of the heart. It has appeared to some of vast importance to fix upon a definite amount of income as each one's yearly contribution. A tenth has been named as the proportion divinely approved, in imitation of Jacob's vow to give a tenth to God of all that he should receive at his hand; and because the Jews were required to pay a tithe of their yearly increase for the support of the Levites. Arguments have been adduced to show that this ratio in charity is obligatory on all; at the same time, it has been acknowledged not to be enjoined in the New Testament. We think, however, the ground untenable; and all efforts to designate this or any other fixed proportion as universally binding, both inexpedient and unscriptural. In the first place, it would not be equal. An alleged requisition, not pressing equally upon all in its ordinary operations, cannot rise out of the necessary relations of the spiritual universe, and therefore is not essential to a moral government. It can be made obligatory on the conscience only by a positive precept from the Great Lawgiver himself. But no ratio of income, universally applicable can be assigned, pressing equally upon all. While one's income may be large, his debts may likewise be large. Another's health may be feeble, his family numerous, and his expenses great; while his neighbor's constitution may be vigorous, his family small, and his necessary expenditures few. Thus circumstances may render it a greater sacrifice for some to give a twentieth, a fiftieth, or even an hundredth of their income, than for others to bestow one half, or indeed, the whole of it, and thousands besides.
