In whom we have redemption through His blood, the forgiveness of sins, according to the riches of His grace… – Ephesians 1:7

For by grace you have been saved through faith, and that not of yourselves; it is the gift of God…- Ephesians 2:8

Beloved, be this always remembered, that it is in the application of redemption, and the personal pardon of any sinner, through the blood of Jesus, that the grace of God is best seen by that sinner. To each one pardon through the Lord Jesus comes, not only according to grace, but “according to the riches of His grace.” I can understand that God should forgive you, all of you. I could hear it with full belief, and it would not astonish me. But that He should pardon me-that I should have the forgiveness of sins, and redemption by blood-that does astonish me. And I believe that any person, under a sense of sin, sees more of the grace of God in his own salvation than in the salvation of anybody else. He may be quite conscious that he has never been a thief, or a drunkard, or a murderer; and yet, when he comes to look at it, he may see reasons why the pardon of sin in his case should be more remarkable than even in the case of a drunkard, or a thief, or a murderer. There may be elements in his own case which may make him seem to have sinned even more grievously than open transgressors, because he transgressed against greater light, with less temptation thereto, and with a direr presumption of rebellion against the Most High. That Jesus died, is unutterable grace; but that He loved me, and gave Himself for me, this is overwhelming grace, and makes the heir of heaven say with emphasis, Blessed be God that, in Jesus, I have redemption through His blood, the forgiveness of sins, according to the riches of His grace! ~ C.H.
