_4thly_, If we assert more than this, namely, that faith is a condition of the covenant of grace, or, as it is expressed in this answer, a condition to interest believers in Christ, we must distinguish between God’s bestowing the blessings of the covenant of grace, pursuant to his secret will, or his eternal purpose; and our having a visible ground, or reason, to claim an interest in them; the former of these cannot be supposed to be conditional, without making God dependent on our act; the latter may, and, I think, ought to be deemed so. Thus faith is a condition, or an internal qualification, without which no one has a warrant to conclude his interest in, or lay claim to the saving blessings of the covenant of grace, so that when it is said to be a condition to interest believers in Christ, in this answer, we are to understand it, as that which evinces our claim to him, or gives us ground to conclude, that we are redeemed by him, and to expect that he will bestow upon us complete salvation. To deny this, would be to suppose, that an unbeliever has a warrant to conclude that Christ loved and gave himself for him, or that he shall be saved by him; which is a doctrine that I cannot but oppose with the greatest detestation, as what contains in it an unwarrantable presumption, and leads to licentiousness, which, I hope, nothing, that has been said on this subject, has the least tendency to do. Thus we have considered how faith may be said to be a condition of our laying claim to an interest in Christ; we proceed, VII. To consider how the grace of God is glorified, in his having ordained, that we should apprehend or discern our interest in Christ, and the blessings of the covenant, by faith. Of all other graces, faith is that which has the greatest tendency to discover to the soul its own vileness, and nothingness; and, indeed, every thing that we behold in Christ its object, has a tendency to abase us in our own sight. Do we, by faith, behold Christ’s fulness? This has a tendency to humble us, under a sense of our own emptiness. Do we look on Christ as the Fountain of all righteousness and strength? This leads us to see that we are destitute hereof in ourselves; so that, as faith beholds all that we have, or hope for, as being founded on, and derived from Christ, and gives us hereupon the greatest sense of our own unworthiness, this is in its own nature adapted to advance the grace of God; and therefore God, in taking this method to apply the blessings of the covenant, requiring faith, as an instrument, hereof, ordained the best expedient, to illustrate, and set forth his own grace as displayed therein. But since it is a very difficult matter to believe, as this grace of faith is the gift and effect of the power of God, we are now to consider,
