From the spirit realm God created the natural realm. The Spirit realm has always existed with the Father. But the natural realm had a beginning and has an end. When God spoke from the realm of the Spirit things came about in the natural. He spoke and bam, there it was. He spoke and things were created. The key is that God spoke. He made man and then He breathed the life of Himself into man. Because we are spirit that has a soul and live in a body we can operate in the spiritual realm. Living in the spiritual realm means that we can know what God knows.
Acts 17:28 ESV for "'In him we live and move and have our being'; as even some of your own poets have said, "'For we are indeed his offspring.'
The Words we speak have power. We are spirit as God is Spirit and we are called to walk in dominion whereby God will back us up. But who are we listening to? Are we still living out of the past life of hurt and rejection or are we living in the new life of the spirit as a child of God? We can speak and declare. Are we listening from our flesh because it hurts? Are we living in the lies of our forefathers?
Declaration as a Spirit-filled person:
I am a spirit, I have a soul, I live in a body, I am walking in dominion over my circumstances, I am righteous, God rules in my life, I speak what He speaks, and I declare what He declares. Because I have His Spirit I can know His mind.
