Just as people do not enter a war in order to enjoy war, but in order to be saved from war, so we too do not enter this world in order to enjoy this world, but in order to be saved from it. People go to war for the sake of something greater than war. So we also enter this temporal life for the sake of something greater: for eternal life. And as soldiers think with joy about returning home, so also Christians constantly remember the end of their lives and their return to their heavenly fatherland.
The chief end of our life is to live in communion with God. To this end the Son of God became incarnate, in order to return us to this divine communion, which was lost by the fall into sin. Through Jesus Christ, the Son of God, we enter into communion with the Father and thus attain our purpose.
