Think of It No More
In C.S. Lewis’ The Silver Chair, Aslan, the figure of Christ, appears to the children: "’I have come,’ said a deep voice behind them. And in less time than it takes to breathe Jill… remembered how she had made Eustace fall over the cliff, and how she had helped to muff nearly all the signs, and about all the snappings and quarrellings. And she wanted to say “I’m sorry” but she could not speak. Then the Lion drew them toward him with his eyes, and bent down and touched their pale faces with his tongue, and said: “Think of it no more."
Early in my Christian life I was led to believe that shortly after entering Heaven all my “snapping’s and quarrellings,” would be portrayed on a giant screen for all the world to see. Now I know that God does not remember even one of my transgressions. “There is no condemnation for those that are in Christ Jesus” (Romans 5:1). Every sin has been buried in the deepest sea, never to be exhumed and examined again. God has said, “Think of it no more!”
Amy Carmichael wrote, “A day or two ago I was thinking rather sadly of the past—so many sins and failures and lapses of every kind. I was reading Isaiah 43, and in verse 24 I saw myself: ‘Thou hast wearied me with your many iniquities.’ And then for the first time I noticed that there is no space between v. 24 and v. 25, ‘I, even I, am He that has blotted out your transgressions for my own sake; and I will not remember your sins.’”
Indeed, when our Lord comes back he will "bring to light the things hidden in darkness and he will disclose the purposes of the heart.” But then “each one will receive his commendation from God” (1 Corinthians 4:5). On that day, he will see only what he has done in and through us. All else will be forgotten.
So, as for my sin… I will “think of it no more!”
