The Person of The Spirit
As believers, we have been called into a life by the Spirit, our dwelling place is in the Spirit. The flesh should not have dominion in your life (Galatians 5:16-17). When you walk in the spirit, you subject yourself to the directives of the Spirit.
Before all of these can be attained, you have to identify with the cross (Gal 2:20). You have to give your life to Christ. It is in doing this that you become a person of the spirit. This means that the Holy Spirit comes to dwell in you. Afterwards, you get baptized with the evidence of speaking in tongues and the Holy Spirit starts to communicate with you.
Also, praying in/with tongues (Eph 6:18, 5:18). When you as a believer pray in the Spirit, you give expression to the Spirit of God inside of you. It is helping your spirit yield more to the Spirit of God.
Rom 8:15, Col 3:2 teaches us to mind the things that are above (this doesn't literally mean looking up to the sky, but fixing your gaze on God Himself, not where He stays exactly). By virtue of the Holyspirit in you, God has come to live in you. That is why it is called the “Spirit of God". Therefore, barricade your mind with the things that be of God and your journey as a person of the spirit will be pleasant.
