And the actions need watchfulness also. They must not only possess the negative quality of abstinence from evil, but the positive stamp of good deeds done. "By their fruits ye shall know them." And the work will be no light one. Peace is to be sought, and the Apostle uses a word which implies that a chase is needful to obtain it. St. Paul has a passage very much in the spirit of St. Peter's teaching here, and the words of which picture distinctly the difficulties which the Christian will have to labour against: "Giving diligence to keep the unity of the Spirit in the bond of peace" (Eph. iv. 3). This tells us why our Apostle urges the pursuit of peace. It is the clasp which binds the Christian communion together. From all sorts of causes men are prone to fall apart, to break the oneness; and peace is able to hold them fast. Hence the diligence in seeking it, the earnestness of the pursuit that it may not elude us.
But when all is done, when men have not been sitting with folded hands waiting and dreaming that peace would come without pursuit, but have laboured for it, they do not always attain to it. "I am for peace," says the Psalmist, "but when I speak, they are for war" (Psalm cxx. 7). And so the disappointed struggler is directed to the sure source of consolation amid discomfiture. The Lord marks his efforts, knows their earnest purpose in spite of their ill-success. He beholds also those who have withstood them, but with far other regard. St. Peter has not quoted what the Psalmist says of their fate: "God will root out the remembrance of them from the earth." God's righteous pilgrim is not forgotten. His prayer is heard, and will be answered for good. No shadow has come between him and God, though his lot seem very dark. Neither can the wrong-doer raise a shadow to screen himself from the all-seeing eyes. All things are naked and open before the eyes of Him with whom we have to do.
