Of the obligation of Christians to perform the duty of charity to the poor.
“THIS duty is absolutely commanded, and much insisted on, in the Word of God. Where have we any command in the Bible laid down in stronger terms, and in a more peremptory urgent manner, than the command of giving to the poor? We have the same law in a positive manner laid down in Lev. 25:35, etc. “And if thy brother be waxen poor, and fallen in decay with thee, then thou shalt relieve him; yea, though he be a stranger or a sojourner, that he may live with thee.” And at the conclusion of verse 38, God enforces it with saying, I am the Lord thy God.
“It is mentioned in Scripture, not only as a duty, but a great duty. Indeed it is generally acknowledged to be a duty, to be kind to the needy. But by many it seems not to be looked upon as a duty of great importance. However, it is mentioned in Scripture as one of the greater and more essential duties of religion. Mic. 6:8, “He hath showed thee, O man, what is good; and what doth the Lord thy God require of thee, but to do justly, to love mercy, and to walk humbly with thy God?” Here to love mercy is mentioned as one of the three great things that are the sum of all religion. So it is mentioned by the apostle James, as one of the two things wherein pure and undefiled religion consists. Jam. 1:27, “Pure religion, and undefiled, before God and the Father, is this, To visit the fatherless and widows in their affliction, and to keep himself unspotted from the world.”
“So Christ tells us, it is one of the weightier matters of the law. Mat. 23:23, “Ye have omitted the weightier matters of the law, judgment, mercy, and faith.” The Scriptures again and again teach us that it is a more weighty and essential thing than the attendance on the outward ordinances of worship. Hos. 6:6, “I desired mercy, and not sacrifice;” Mat. 9:13 and 12:7. I know of scarce any duty which is so much insisted on, so pressed and urged upon us, both in the Old Testament and New, as this duty of charity to the poor.”
