The one who knows God will follow the Lord's footsteps, bearing the cross of the Savior. It is said, "The world is crucified to him and he to the world." The Lord says, "He who loses his life will save it." We can "lose our lives" in one of two ways. First, we can risk our lives just as the Lord did for us. Secondly, we can separate our lives from the customary things of this world.
Bearing the cross means to separate our souls from the delights and pleasures of this life. If you do this, you will find your life again - resting in the hope of what is to come. Dying to ourselves means being content with the necessities of life. When we want more that these necessities it is easy to sin.
St. Clement of Alexandria
