The saints' and the faithful' are not two sets of people, but one. The Apostle starts, as it were, on the surface, and goes down; takes off the uppermost layer and lets us see what is below it; begins with the flowers or the fruit, and then carries us to the root. The saints are saints because they are first of all faithful. Faithful' here, of course, does not mean, as it usually does in our ordinary language, true' and trusty,"reliable' and keeping our word,' but it means simply believing'; having faith, not in the sense of fidelity, but in the sense of trust.
So, then, here is Paul's notion--and it is not only Paul's notion, it is God's truth--that the only way by which a man ever comes to realise that he belongs to God, and to yield himself in glad surrender to His uses, and so to become pure and holy like Him whom He loves and aspires to, is by humble faith in Jesus Christ. If you want to talk in theological terminology, sanctification follows upon faith. It is when we believe and trust in Jesus Christ that all the great motives begin to tell upon life and heart, which deliver us from our selfishness, which bind us to God, which make it a joy to do anything for His service, which kindle in our hearts the flame of fructifying and consecrating and transforming love. Faith, the simple reliance of a desperate and therefore trusting heart upon Jesus Christ for all that it needs, is the foundation of the loftiest elevation and attainment of the Christian character. We begin down there that we may set the shining topstone of Holiness to the Lord' upon the heaven-pointing summit of our lives.
Note how here Paul sets forth the object of our faith and the blessedness of it. I do not think I am forcing too much meaning into his words when I ask you to notice with what distinct emphasis and intentional fulness he employs the double name of our Lord here to describe the object upon which our faith fixes, Faithful in Christ Jesus.' We must lay hold of the Manhood, and we must lay hold of the office. We must rest our soul's salvation on Him as our brother, Jesus who was incarnate in sinful flesh for us; and we must also rest it on Him as God's anointed, who came in human flesh to fulfil the divine loving-kindness and purposes, and in that flesh to die. A faith in a Jesus who was not a Christ would not sanctify; a faith in a Christ who is not Jesus would be impalpable and impotent. We must take the two together, believing and feeling that we lay hold upon a loving Man, bone of our bone and flesh of our flesh'; and also upon Him who in His very humanity is the Messenger and Angel of God's covenant; the Christ for whom the way has been being prepared from the beginning, and who has come to fulfil all the purposes of the divine heart.
And notice, too, how there is suggested here also, the blessedness of that faith, inasmuch as it is a faith in Christ. The New Testament speaks in diverse ways about the relation between the believing soul and Jesus Christ. It sometimes speaks of faith as being towards Him, and that suggests the going out of a hand that, as it were, stretches towards what it would lay hold of. It sometimes speaks of faith as being on Him, which suggests the idea of a building on its foundation, or a hand leaning on a support. And it sometimes speaks, as here, of faith being in Him,' which suggests the folded wings of the dove that has found its nest, the repose of faith, the quiet rest in the Lord, and waiting patiently for Him.' Such trust so directed is the one condition of such tranquillity. Then, again, note a Christian is all that he is because he is in Christ.' That phrase in Him' is in some sense the keynote of this Epistle to the Ephesians. If you will look over the letter, and pick out all the connections in which the expression in Him' occurs, I think you will be astonished to see how rich and full are its uses, and how manifold the blessings of which it is the condition. But the use which Paul makes of it here is just this--everything in our Christian life depends upon our being rooted and grafted in Jesus. Dear brethren, the main weakness, I believe, of what is called Evangelical Christianity has been that it has not always kept true to the proportionate prominence which the New Testament gives to the two thoughts, Christ for us,' and Christ in us.' For one sermon that you have heard which has dwelt earnestly and believingly on the thought of the indwelling Christ and the Christian indwelling in Him, you have heard a hundred about the Sacrifice on the Cross for sins, and the great atonement that was made by it. Those of you, who have listened to me from Sunday to Sunday, know that I am not to be charged with minimising or neglecting that truth, but I want to lay upon all your hearts this earnest conviction, that a gospel which throws into enormous prominence Christ for us,' and into very small prominence Christ in us,' is lame of one foot, is lopsided, untrue to the symmetry and proportion of the Gospel as it is revealed in the New Testament, and will never avail for the nourishment and maturity of Christian souls. Christ for us' by all means, and for evermore, but Christ in us,' or else He will not be for us.'
