Spiritual or Worldly

For they that are after the flesh do mind the things of the flesh; but they that are after the Spirit, the things of the Spirit. Romans.8:5.

God has a very big purpose in revealing this verse to Apostle Paul. The verse doesn't explain about two types of souls (Spiritual and Worldly), but it draws a circumference to his deeds.

Imagine with me that a man standing before a mirror in a room which is lightened by an electricity bulb. Assume that the man as body, image in the mirror as soul, the shadow of the man is his spirit, the room is the world and the light to as spirit of darkness and to the Holy Spirit in continuation of this article.
The image in the mirror (soul) demands the man (body) all its vices and his shadow (spirit) which depends upon the light (spirit of darkness) emitting from the bulb acts as the body acts. The body which is influenced by the soul which is watching the known world in the emission of light (spirit of darkness) can only fulfill its vices and the spirit (shadow) has nothing to do but just follow the way the body acts. This man who is driven by his soul will live a worldly life.

On the other hand, imagine a man (body) standing in a vast open space (world yet to be evangelized) under the sun light (the Holy Spirit). Because, he is not standing before a mirror, he cannot be influenced by his soul (image in the mirror) and because he is not under the (light of darkness) electricity bulb, his spirit (shadow) is not confined to the room (world) but can reach beyond the horizons and above all his spirit (shadow) is influenced by the sun light (the Holy Spirit). As the sun emits its light (the Holy Spirit) and travels from east to west so the shadow (spirit) spreads; the spreading of the shadow is the thirst of the spirit to evangelize Christ to the nations. This is all what Jesus wanted from us. Because there is no mirror/image in the mirror (soul), the body will be influenced by the spirit (shadow) which is again influenced emission of the sun light (the Holy Spirit). This is living after the Spirit.

Those who live after the Spirit do keep this commandment of the Lord.
Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Amen.
Matthew.28:19,20
