Gen. 1:1 says, "In the beginning God!" This word for God is Elohiym (Eloheem) and it means, God's. It is used when referring to the plurality of God. More than one. It is used throughout the Bible when speaking of God.
The word 'beginning' used here is the Hebrew word, reshiyth, (ray-sheeth) and means, the first in place, time, order or rank. Specifically a firstfruit or first principal thing.
Remember Paul said in 1 Cor. 15:22,

"For as in Adam all die, even so in Christ shall all be made alive. 23But every man in his own order: Christ the firstfruits; afterward they that are Christ's at his coming."

May I suggest to you that Paul said, "Christ the firstfruits!" and not Christ then the firstfruits. Then he said all that are Christ's at His coming. This is everyone.

Going back to Gen. 1, this should read, "In the firstfruits Elohiym!" This means that in the beginning God was a body and in the ending God is a body. El Elyon, which is the most high God, the one we call Father, became revealed in a body which the bible refers to as Elohiym. In this body El Elyon has the freedom to express Himself. Nothing was there to hinder Him from expressing Himself in that body. So, when El Elyon spoke His will it was carried out through that body of Elohiym! Paul said in Col.1:15-20,

"He (Jesus)is the image of the invisible God, the firstborn over all creation. 16For by him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things were created by him and for him. 17He is before all things, and in him all things hold together. 18And he is the head of the body, the church; he is the beginning and the firstborn from among the dead, so that in everything he might have the supremacy. 19For God was pleased to have all his fullness dwell in him, 20and through him to reconcile to himself all things, whether things on earth or things in heaven, by making peace through his blood, shed on the cross."

We were in Christ in the beginning and through the body of Christ the world was created. When God said, "Let there be!" there was nothing to prevent this from happening. God didn't speak His word and the creation said, "Wait a minute!" "Let me pray about it!" Everything was so in union with God that when He spoke there was an immediate response to the command of God. Nothing outside of Him turned to Him to oppose Him. There was no opinion that was contrary to His plan.

If we are to be reconciled, or brought back to what used to be, or to that old time religion, then we have to be brought back to the first fruits in Elohiym. This can only be done by the renewing of our minds that Paul spoke about in Rom. 12:1. There has to become in us nothing that opposes the will of God. That cannot happen unless we know the will of God and Jesus gave us the will of God in John 15:14 & 17,
"You are my friends if you do what I command…….This is my command: Love each other….Then the Father will give you whatever you ask in my name."
Jesus also said in Matt. 18:3-5,

"Verily I say unto you, Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven. 4Whosoever therefore shall humble himself as this little child, the same is greatest in the kingdom of heaven. 5And whoso shall receive one such little child in my name receiveth me."
That word, 'converted' means to turn and go back. We have to be willing to turn around and go back to Elohiym. Back to that place in time when we were with Him and our thinking was in alignment with His. Jesus used a little child as an example of how we are to be in our response to His Word.

Consider the body that Jesus demonstrated when he was resurrected. With it He could appear in a locked room without coming through a door. He could also eat fish with the disciples. The body that Adam had originally was a body made from the dust of the earth. It stands to reason that this body was a body of flesh like that of the animals. The difference was that Elohiym breath the breath of life, which is the Spirit, into Adam and he became a living soul. (mind, will & emotions)
For all practical purposes Jesus, when He was resurrected, had a body that could eat, and be touched but could also be transformed into a spirit body when He willed.

Also consider what happened of the Mount of Transfiguration.
