X. But when the saints sometimes appear to urge their own righteousness as an argument in their supplications with God,—as when David says, “Preserve my soul; for I am holy;”[291] and Hezekiah, “I beseech thee, O Lord, remember now how I have walked before thee in truth, and have done that which is good in thy sight,”[292]—their only design in such modes of expression is, from their regeneration to prove themselves to be servants and sons of God, to whom he declares he will be propitious. He tells us by the Psalmist, (as we have already seen,) that “his eyes are upon the righteous, and that his ears are open unto their cry;”[293] and again, by the apostle, that “whatsoever we ask, we receive of him, because we keep his commandments;”[294] in which passages he does not determine the value of prayer according to the merit of works; but intends by them to establish the confidence of those who are conscious to themselves, as all believers ought to be, of unfeigned integrity and innocence. For the observation in John, made by the blind man who received his sight, that “God heareth not sinners,”[295] is a principle of Divine truth, if we understand the word _sinners_, in the common acceptation of Scripture, to signify those who are all asleep and content in their sins, without any desire of righteousness; since no heart can ever break out into a sincere invocation of God, unaccompanied with aspirations after piety. To such promises, therefore, correspond those declarations of the saints, in which they introduce the mention of their own purity or innocence, that they may experience a manifestation to themselves of what is to be expected by all the servants of God. Besides, they are generally found in the use of this species of prayer, when before the Lord they compare themselves with their enemies, from whose iniquity they desire him to deliver them. Now, in this comparison, we need not wonder, if they produce their righteousness and simplicity of heart, in order to prevail upon him by the justice of their cause to yield the more ready assistance. We object not, therefore, to the pious heart of a good man making use before the Lord of the consciousness of his own purity for his confirmation in the promises which the Lord has given for the consolation and support of his true worshippers; but his confidence of success we wish to be independent of every consideration of personal merit, and to rest solely on the Divine clemency.
