For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing and even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart. Hebrews 4:12
It is being taught that, just as God is triune, man is also. We are body, soul, spirit. We are , after all, made in God's image. According to this philosophy, we are little gods! If an impertinent person (I would never do this) were to ask if man is Father, Son, and Holy Spirit, the answer would be, "Certainly not!" But, the argument maintains, man has three of something, and therefore is God-like.
The quest to elevate man never ceases in some quarters, as does the quest to make the church the all-in-all. Most sermons are about how to be better and more successful, though God is mentioned as a kind of coach to aid us in our goal of self-improvement.
The quote from Hebrews speaks of man's heart, another aspect of our humanity. Body, soul, spirit, mind, and heart--that basically defines man. Not divine, but descriptive of our natures.
Did I say "soul"? We all have one, but like the rest of us, it ceases when we stop breathing.
Are we God-like? We should try to be Christ-like. How well are we doing?
