It is because He wept, i.e., loved His friend Lazarus and had pity on him, that He had the power of restoring life to him. …God is Love, and it is love that creates life; it is love that weeps at the grave and it is, therefore, love that restores life… This is the meaning of these Divine tears. They are tears of love and, therefore, in them is the power of life. Love, which is the foundation of life and its source, is at work again recreating, redeeming, restoring the darkened life of man: “Lazarus, come forth!” And this is why Lazarus Saturday is the real beginning of both: the Cross, as the supreme sacrifice of love, and the Common Resurrection, as the ultimate triumph of love.
Fr. Alexander Schmemann in a homily for the Saturday of Lazarus (published in The Christian Way, 1961).
