VIII. This inward witness of the truth of christianity, is, or should be, always growing and improving. The testimony increases as the divine love increases; the greater the degree of holiness we arrive at, the more are we confirmed in the truth of christianity the testimony grows stronger, 2 Cor. iii. 18. You find that text approves of what I have now argued. When the apostle had been distinguishing between the religion of the law, and that of the gospel; that the one was covered with a veil, but under the other this veil was taken away: We, says he, under the gospel, _with open face beholding, as in a glass, the glory of the Lord, are changed into the same image from glory to glory. We who behold the face of Christ Jesus_ in his gospel, we who here see a God reconciled in and by the death of his Son, we who see the holiness of Christ here described, copied, and exemplified, _we are changed into the same image_. The image of Christ is transcribed upon our natures, we go on from one degree of it to another; we are changed _from glory to glory_, from one degree of glorious holiness to another: thereby the gospel appears to have a fairer, a brighter, and a stronger evidence. Thence it comes to pass, that when christians have grown to a good degree of strength in faith, and great measures of holiness in this world, all the temptations that they meet with to turn them aside from the doctrines of Christ, _are esteemed but as straw and stubble_; they cannot move nor stir them from the faith that is in Jesus, because the evidence hath grown strong with years: and as they have attended long upon the ministration of this gospel, they have found more and more of this eternal life wrought in their hearts; they have got nearer to heaven, they have pressed on continually towards perfection, they have found sweet assurance of the pardon of sin in their conscience, and diviner sensations of the love of God communicated to them, and their own love both to God and man increasing; they have found their hearts more averse to all iniquity, they have felt themselves rising higher and higher above this world, as they have come nearer to the end of their days; and a holy contempt of this world has grown bolder: They take greater delight in God, and more gustful satisfaction in his worship, and in his company: Their zeal for his honour is warmer and stronger; they are perpetually employing themselves in contrivances for the glory of God among men. Thus in every part of this spiritual life the testimony increases, the evidence grows brighter, as eternal life advances in them.
