In God there is peace and, therefore, eternal life means serenity. It means a life liberated from the fears which haunt the human situation. In God there is power and, therefore, eternal life means the defeat of frustration. It means a life filled with the power of God and, therefore, victorious over circumstance. In God there is holiness and, therefore, eternal life means the defeat of sin. It means a life clad with the purity of God and armed against the soiling infections of the world. In God there is love and, therefore, eternal life means the end of bitterness and hatred. It means a life which has the love of God in its heart and the undefeatable love of man in all its feelings and in all its action. In God there is life and, therefore eternal life means the defeat of death. It means a life which is indestructible because it has in it the indestructibility of God himself.

—Wm. Barclay, on 1 Jn 5.11-13
