A friend in Ireland once met a little Irish boy who had caught a sparrow. The poor little bird was trembling in his hand, and seemed very anxious to escape. The gentleman begged the boy to let it go, as the bird could not do him any good; but the boy said he would not; for he had chased it three hours before he could catch it. He tried to reason it out with the boy, but in vain. At last he offered to buy the bird; the boy agreed to the price, and it was paid. Then the gentleman took the poor little thing and held it out on his hand. The boy had been holding it very fast, for the boy was stronger than the bird, just as Satan is stronger than we, and there it sat for a time, scarcely able to realize the fact that it had got liberty; but in a little while it flew away, chirping, as if to say to the gentleman, "Thank you! thank you! you have redeemed me." That is what redemption is -- buying back and setting free. So Christ came back to break the fetters of sin, to open the prison doors and set the sinner free. This is the good news, the gospel of Christ -- "Ye are not redeemed with corruptible things, as silver and gold, but with the precious blood of Christ."
