III. The only remaining question is as to our own part in the great plan of mercy. Because we are intelligent and moral creatures, God does not save us without our own concurrence. To every one who desires to receive this twofold gift--the gift of pardon and of sanctification--a certain disposition is necessary. That disposition is in the Scriptures called "faith." Faith is the divinely-appointed condition of salvation. The terms are simple, but they are indispensable. Scripture, in every part, recognises and imposes them. From the earliest times they have been complied with, as in the sacrifices of Abel, Noah, and Abraham. It was this same principle of faith that gave validity to the worship under the Mosaic dispensation. So the Lord Jesus Christ, who healed men's physical diseases as types of the diseases of the soul, always demanded faith as the condition of His working. As it was with Christ, so it was with His apostles. Thus Paul said to the Philippian jailer, "Believe on the Lord Jesus Christ, and thou shalt be saved." All this shows to us that whilst, on the one hand, we are saved by grace; on the other, we have no participation in the grace which saves, except by the exercise of our own faith in the Saviour. What is this faith? It may be considered in its principle, and in its application. In its principle, it is a general conviction that the Bible is the Word of God, and that what He says therein should receive our assent; or, in other words, should be accepted by us as _true_. In its application, it is the belief of God's Word as it respects _ourselves_. It is this which Paul commends to the Philippian jailer. When a man, under the burden of his sin, says, "I am lost; I cannot save myself; save me, Lord!" we have an illustration of this applied faith--a sense of personal misery, a sense of personal helplessness, a sense of a Saviour willing to save him personally, and a direct appeal to that Saviour for salvation. From the moment of such a prayer, there is not a single promise of Scripture that such a man may not make his own. A promised pardon, a promised Spirit, a promised heaven--all are his! The essence of the faith is in the conviction which expresses itself thus: "Jesus Christ is not only able and willing to be the Saviour of all men, but He is my Saviour." Such a faith brings Christ and the soul together in precisely those relations in which He is the Saviour, and in which the soul is saved.
