This is from Peter Kreeft's book, "Heaven, The Heart's Deepest Longing."
pg 130 - "The soul makes the difference between life and death to the body, and the spirit makes the difference between life and death to the soul. A body without a soul is not a living body but a corpse."
pg 131 - "Spirit has only two choices: for or against God."
pg 134 - "Joy is in the spirit, not in the soul; and soul is at least partly under our control. Spirit is not. Spirit rules soul, but soul does not rule spirit. We can control pleasure and even happiness to an extent, but never joy; it is a sheer gift of God."
Most of us spend our lives under the influence of our bodies and its needs. Some venture deeper into self and find their soul. But few go deep enough to enter into their spirit which is where God dwells within each of us. It is only through deep prayer that we develop our relationship with God and discover who we really are and God's plan for us. We truly do have only two choices, either for God or against Him. Which is your choice? God bless!!
