One of the primary goals for the believer is to become spiritual (led by our spirit man, the real you), not carnal (led by our flesh). You are a spirit, you have a soul, and you live in a body. Just as man has learned how to develop his body and his soul, you can develop your spirit man. This is what every believer should do, for when your spirit man is dominate, this new nature made in the image of God will control and direct you. To develop your spirit man you need to:
1. Meditate on the Word of God.
2. Practice the Word.
3. Give the Word first place.
4. Obey your conscience (the voice of your spirit).
5. Pray in the Spirit.
6. Walk in love.
Do these things and you will grow spiritually. As you do the old flesh nature will no longer rule you and you will be led by your spirit man.
