As a matter of fact, there was a far profounder and more inward conviction of sin among the Jews than in any heathen nation. Contrast the wailings of many a psalm with the tone in Greek or Roman literature. No doubt there is a law written on men's hearts which evokes a lower measure of the same consciousness of sin. There are prayers among the Assyrian and Babylonian tablets which might almost stand beside the Fifty-first Psalm; but, on the whole, the deep sense of sin was the product of the revealed law. The best use of our consciousness of what we ought to be, is when it rouses conscience to feel the discordance with it of what we are, and so drives us to Christ. Law, whether in the Old Testament, or as written in our hearts by their very make, is the slave whose task is to bring us to Christ, who will give us power to keep God's commandments. Another purpose of the law is stated in verse 21, as being to bear witness, in conjunction with the prophets, to a future more perfect revelation of God's righteousness. Much of the law was symbolic and prophetic. The ideal it set forth could not always remain unfulfilled. The whole attitude of that system was one of forward-looking expectancy. There is much danger lest, in modern investigations as to the authorship, date, and genesis of the Old Testament revelation, its central characteristic should be lost sight of; namely, its pointing onwards to a more perfect revelation which should supersede it. II. Paul's view of universal sinfulness. He states that twice in this passage (vs. 20 to 24), and it underlies his view of the purpose of law. In verse 20 he asserts that 'by the works of the law shall no flesh be justified,' and in verses 23 and 24 he advances from that negative statement to the positive assertion that all have sinned. The impossibility of justification by the works of the law may be shown from two considerations: one, that, as a matter of fact, no flesh has ever done them all with absolute completeness and purity; and, second, that, even if they had ever been so done, they would not have availed to secure acquittal at a tribunal where motive counts for more than deed. The former is the main point with Paul. In verse 23 the same fact of universal experience is contemplated as both positive sin and negative falling short of the 'glory' (which here seems to mean, as in John v. 44, xii. 43, approbation from God). 'There is no distinction,' but all varieties of condition, character, attainment, are alike in this, that the fatal taint is upon them all. 'We have, all of us, one human heart.' We are alike in physical necessities, in primal instincts, and, most tragically of all, in the common experience of sinfulness.
