“I will rejoice in Thy salvation.”- Psalm 9:4

You have salvation wrapped up in the gift of the person of Jesus Christ. All of it lies in Christ. Because He died, our sin is put away. Because He lives, we shall live also. And Christ is the pure gift of God. All salvation is in Him, and, therefore, all salvation is thus procured by God. It is God’s salvation. And what is more, God not only plans and procures, but He also applies salvation… All believers will confess that they are God’s workmanship, created anew in Christ Jesus. “No man can come unto Me except the Father which hath sent Me draw Him.” There is a want (lack) of power. “Ye will not come unto Me that ye might have life.” There is a want (lack) of will, and the Spirit of God, therefore, applies the salvation which God has planned, and which God has provided. And as the first application of this salvation is of God, so is it all the way through.

He is Alpha and Omega, the beginning and the ending. “Salvation is of the Lord,” from first to last. He makes the rough draft of it, in conviction, upon our conscience; He goes on to complete the picture; and if there be one touch in the picture that is not of God, it is a blot upon it. If there be anything of the flesh, it will have to be wiped out; it is not consistent with the work of God. Of God is it in all respects. Now we know that this salvation is of God, not only because we are told that He planned it, and provided it, and applies it, but because it has the marks of God upon it.~ C.H. Spurgeon
