This is the slavery from which he above all came to save us. God cares about the total liberation of the human person, a liberation not only concerns physical and external conditions, but is first and foremost a liberation of the heart. Our sin has disrupted God's plan, and its effects are not only felt in human life but also in creation itself. This cosmic dimension of the effects of sin becomes almost tangible in ecological disasters. No less worrying is the damage caused by sin to the human psyche, to human biology itself.
Sin is devastating.
It drives peace from hearts and causes a chain of sufferings in human relationships. I imagine how frequently you can observe this truth as you reflect on your personal histories or listen to those of your cell mates. This is precisely the slavery from which the Spirit of God comes to deliver us. Therefore, he, the Spirit of Jesus Christ, must be the one who works in your hearts, dear brother and sister prisoners. The Holy Spirit must pervade this prison where we are meeting and all the prisons of the world.
