Let all those that seek Thee rejoice and be glad in Thee: and let such as love Thy salvation say continually, Let God be magnified. -Psalm 70:4

When the Lord pardoned our sins, He did not pardon half of them, and leave some of them on the book, but with one stroke of the pen He gave a full receipt for all our debts. When we went down into the fountain filled with blood, and washed, we did not come up half-clean, but there was no spot nor wrinkle upon us-we were white as driven snow. Glory be to God for such a rich salvation as this. And He did not in that day save us with a perhaps and a chance salvation that set us on a rock, and say, “Keep yourself there-you must depend upon yourselves”, but this was the covenant He made with us, “A new heart also will I give thee, and a right spirit will I put within thee.” It was a complete salvation, which would not permit a failure. The salvation, which is given to the soul that believes is on this wise, “I give unto My sheep eternal life, and they shall never perish, neither shall any pluck them out of My hand.” “The water that I shall give him shall be a well of water springing up unto everlasting life.” I believe the perseverance of the saints to be the very gem of the gospel. I could not hold the truth of Scripture if this could be disproved to me, for every page seems to have this upon it, if nothing else, that “the righteous shall hold on his way, and he that hath clean hands shall wax stronger and stronger.” In this my soul rejoices, that I have a salvation to preach to you which, if you receive it, will effectually save you if your hearts are given to Christ, and will keep you, and preserve you, and bring you into the eternal kingdom of His glory. I will rejoice in the certain and abiding character of that salvation. Oh! there is enough in the salvation of Christ to make heaven full of bliss; there is enough to make us full of praise. Let us take up the theme; let us talk by the way to one another about it; let us talk to sinners about it; let us recommend religion by our cheerfulness. ~ C.H. Spurgeon
