 Life is not desirable unless it is a certain kind of life. Here we have the clue. Aionios ( G166) is the adjective which is repeatedly used to describe God. In the true sense of the word only God is aionios ( G166) , eternal; therefore eternal life is that life which God lives. What Jesus offers us from God is God's own life. Eternal life is life which knows something of the serenity and power of the life of God himself. When Jesus came offering men eternal life, he was inviting them to enter into the very life of God.
