In John viii. 32 we read, “Ye shall know the truth and _the truth shall set you free_.” In this verse it is the truth, or the Word of God, that sets us free from the power of sin and gives us victory. And in Ps. cxix. 11 we read, “_Thy Word_ have I hid in my heart, that I might not sin against Thee.” Here again it is the indwelling Word that keeps us free from sin.

Here the power of the Spirit manifests itself, not merely in giving us victory over sin but in four things:
