Consider its worth as a defence. The Apostle in one place speaks about 'the shield of faith.' But there is nothing in the belief that I am safe to make me safe. It is very often a fatal blunder. All depends upon that or Him, to which or whom I am trusting for my safety. Put yourself beneath the true Shield--'The Lord God is a sun and shield'--and then you will be safe. Your way of running into the strong tower which alone, with its massive walls, protects us from all danger and from all sin, is by trusting Him.
Just as light things on a ship's deck have to be lashed in order to be secured and lie still, you and I have to lash ourselves to Jesus Christ; then, not by reason of the lashings, but by reason of Him, we are fastened and secured.
Consider the worth of faith as a means of purifying. This very Apostle, in his great speech in Jerusalem, when vindicating the reception of the Gentiles into the Church, spoke of God as having 'purified their hearts by faith.' And here again, I say, there is no cleansing power in the act of trust. Cleansing power is in that which, by the act of trust, comes into my heart. Faith is not simple receptivity, not mere passive absorbing of what is given, but it is the active taking by desire as well as by confidence. And when we trust in Jesus Christ, His blood and righteousness, there flows into our hearts that Divine life which, like a river turned into a dung-heap, will sweep all the filth before it. You have to get the purifying power by faith. Ay! and you have to utilise the purifying power by effort and by work. 'What God hath joined together, let not men put asunder.'
III. Now, lastly, note the identity of faith.
'_Like_ precious,' says Peter, and, as I said, there may be defended a double application of the word, and two sets of pairs of classes may be supposed to have been in his mind. I do not discuss which of these may be the case, only I would suggest to you that from this beautiful gathering together of all the diversities of the Christian character, conception, and development into one great whole, we are taught that the one thing that makes a Christian is this trust. That is the universal characteristic; that is uniform, whatever may differ. Ah! how much and how little it takes to make a Christian. 'Only faith?' you say. Yes, thank God! not this, or that, not rites, not anything that a priest can do to you. Not orthodoxy; not morality; these will come, but trust in Christ and His blood and righteousness. England is a Christian country; is it? This is a Christian congregation; is it? You are a Christian; are you? Are you trusting in that Christ? If you are not; no! though you be orthodox up to the eyebrows, and though seven or seven hundred sacraments may have been given to you, and though you be a clean living man--all that does not make a Christian, but _this_ does--'Like precious faith with us in the righteousness of God and our Saviour.'
Again, this great thought of the identity or uniformity of the one characteristic may suggest to us how Christian faith is one, under all varieties of form. There never has been in the Christian Church again, notwithstanding all our deplorable divisions and schisms, such a tremendous cleft as there was in the primitive Church between the Jewish and Gentile components thereof. But Peter flings this flying bridge across that abyss, and knits the two sides together, because he knows that away out yonder, amongst the Gentiles, and here in the little circle of the Jewish believers, there was the one faith that unifies all.
So, dear friends, there should be the widest charity, but no vagueness; for the Christian faith in Him which unifies and bridges over all differences, mental and theological, is the Christ by whose blood we are cleansed, with whose righteousness we are made righteous.
