Why does Peter put in the very centre here 'the sufferings of Christ'? That suggests another thought, that amongst these facts which, taken together, make the Gospel, the vital part, the central and the indispensable part, is the story of the Cross. Now what Christ said, not what Christ did, not what Christ was, beautiful and helpful as all that is, but to begin with what Christ bore, is the fact that makes the life of the Gospel. And just as He is the centre of humanity, so the Cross is the centre of His work. Why is that? Because the deepest need of all of us is the need to have our sins dealt with, both as guilt and as power, and because nothing else in the whole story of Christ's manifestation deals with men's sins as the fact of His death on the Cross does, therefore the sacrifice and sufferings are the heart of the Gospel.
And so, brethren, we have to mark that the presentation of Christian truth which slurs over that fact of the Sacrifice and Atonement of Jesus Christ, has parted with the vital power which makes the story into a gospel. It is no gospel to tell a man that Jesus Christ died, unless you go on to say He 'died for our sins according to the Scriptures.' And it is no gospel to talk about the beauty of His life, and the perfectness of His example, and the sweetness of His nature, and the depth, the wisdom, and the tenderness of His words, unless you can say this is 'the Lamb of God,' 'the Word made flesh,' 'who bare our sins, and carried our sicknesses and our sorrows.' Strike out from the gospel that you preach 'the sufferings of Christ,' and you have struck out the one thing that will draw men's hearts, that will satisfy men's needs, that will bind men to Him with cords of love. 'I, if I be lifted up, will draw all men unto Me.' So, wherever you get what they call an ethical gospel which deals with moralities, and does not impart the power that will vitalise moralities, and make them into thankful service and sacrifices, in return for the great Sacrifice; wherever you get a gospel that falters in its enunciation of the sufferings of Christ, and wherever you get a gospel that secularises the Christian service of the Sabbath, and will rather discuss the things that the newspapers discuss, and the new books that the reviewers are talking about, and odds and ends of that sort that are thought to be popular and attractive, you get a gospel _minus_ the thing that, in the Old Testament and in the New alike, stands forth in the centre of all. 'We preach Christ crucified'; it is not enough to preach Christ. Many a man does that, and might as well hold his tongue. 'We preach Christ crucified.' And the same august Figure which loomed before the vision of prophets, and shines through many a weary age, stands before us of this generation; ay! and will stand till the end of the world, as the centre, the pivot of human history, the Christ who has died for men. The Christ that will stand in the centre of the development of humanity is the Christ that died on the Cross. If your gospel is not that, you have yet to learn the deepest secret of His power.
III. Once more, here we have Christ and His Cross as the study of angels.
'Which things the angels desire to look into.' Now, the word that Peter employs there is an unusual one in Scripture. Its force may, perhaps, be best conveyed by referring to one of the few instances in which it is employed. It is used to describe the attitude of Peter and John when they stooped down and looked into the sepulchre. Perhaps there may be a reference in Peter's mind to that incident, when he saw the 'two angels ... sitting, the one at the head, and the other at the feet, where the body of Jesus had lain.' Perhaps, also, there floats in his mind some kind of reference to the outspread wings and bended heads of the brooding cherubim who sat above the Mercy-seat, gazing down upon the miracle of love that was manifested beneath them there. But be that as it may, the idea conveyed is that of eager desire and fixed attention.
