“There is no difference, for all have sinned and fall short of the glory of God, and are justified freely by his grace through the redemption that came by Christ Jesus.” (Romans 3:22-24)

What makes Christianity different from all other religions in the world? C.S. Lewis, a longtime defender of the gospel said, “Oh, that’s easy. It’s grace.”
Grace changes everything in the life of a believer. And there isn’t a better example of the difference that grace made in one’s life than in the life of John Newton, author of America’s favorite hymn, Amazing Grace.
Newton understood what it meant to be a “wretch”. He commanded an English slave ship in the 1700’s and brought thousands of slaves to this country during his lifetime. Newton showed no compassion for his cargo. He chained them below the decks to prevent suicides. If a slave became ill during the voyage, he was tossed overboard to prevent the infection from spreading.
All that changed one night when Newton’s ship almost sunk. He gave his life to Christ and spent the rest of his days scratching his head in disbelief over the change. When he was 82, he said, “My memory is nearly gone, but I remember two things, that I am a great sinner, and that Christ is a great savior.”
Newton’s song reminds us all about how wretched we are. In fact, the Bible says that without Jesus, we are dead in sin. Indeed, we have no chance, but for the grace of God. Grace is the unmerited favor of God. As one writer puts it, “The very heart of the gospel is the truth that God accepts us with no conditions when we put our trust in the atoning sacrifice of His Son.” That’s why it has long been said that the best way to describe grace is by using the very letters that make up the word: G-R-A-C-E, 

G - God’s

R - Riches

A - At

C - Christ’s

E - Expense.
So our faith teaches us that grace can only come from God. But did you know that grace has a unique purpose of its own? The Bible says that grace “teaches us to say ‘No’ to ungodliness and worldly passions, and to live self-controlled, upright and godly lives in this present age.” (Titus 2:11)
John Newton was no different than the rest of us which is why his song means so much. It reminds us there is only one thing that distinguishes one sinner from another: Grace. And when you think about that, it really is amazing!
