When we get out of the gospels into the epistles we find ourselves face to face with the same tragic and glorious fact. Peter's first letter is not a theological treatise. He is not writing a dissertation on the person of Christ, or attempting to give any interpretation of the death of Jesus; he is dealing with very practical matters. He exhorts the Christians who are discouraged and downhearted to hold up their heads and to be brave. It is interesting to see how again and again he puts the cross behind them in order to keep them from slipping back. "Endure," he says, "because Christ suffered for us. Who his own self bore our sins in his own body on the tree." The Christians of that day had been overtaken by furious persecution. They were suffering all sorts of hardships and disappointments. But "suffer," he says, "because Christ has once suffered for sins, the just for the unjust, that he might bring us to God." Certainly the gospel, according to St. Peter, was: Christ died for our sins. Read the first letter of St. John, and everywhere it breathes the same spirit which we have found in the gospels and in St. Peter. John punctuates almost every paragraph with some reference to the cross. In the first chapter he is talking about sin. "The blood of Jesus Christ," he says, "cleanses us from all sins." In the second chapter he is talking about forgiveness, and this leads him to think at once of Jesus Christ, the righteous, "who is the propitiation for our sins, and not for ours only but for the sins of the whole world." In the third chapter he is talking about brotherly love. He is urging the members of the Church to lay down their lives, one for another, "Hereby perceive we the love of God, because he laid down his life for us." In the fourth chapter he tells of the great mystery of Christ's love: "Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins." To the beloved disciple evidently the great fact of the Christian revelation is that Christ died for our sins. But it is in the letters of Paul that we find the fullest and most emphatic assertion of this transcendent fact. It will not be possible for me to quote to you even a half of what he said on the subject. If you should cut out of his letters all the references to the cross, you would leave his letters in tatters. Listen to him as he talks to his converts in Corinth: "First of all I delivered unto you that which I also received, how that Christ died for our sins." That was the foremost fact, to be stated in every letter and to be unfolded in every sermon. To Saul of Tarsus, Jesus is not an illustrious Rabbi whose sentences are to be treasured up and repeated to listening congregations; He is everywhere and always the world's Redeemer. And throughout all of Paul's epistles one hears the same jubilant, triumphant declaration, "I live by the faith of the Son of God, who loved me and gave himself for me."
