It is becoming obvious to physicists, astronomers and science in general that we live in a multi-dimensional universe. We are aware of 4 space-time dimensions and the current thinking is that there are actually 10 dimensions.
See https://phys.org/news/2014-12-universe-dimensions.html for a brief explanation.
what comprises the other dimensions and what my inhabit them is up for question and debate.
What we know is that we inhabit this dimension and have responsibility for the types of lives that we live within it. God created mankind to inhabit the earth and to have dominion over it. Mankind’s rebellion and subsequent expulsion from the garden has not negated that first declaration by God of mankind’s Dominion.
In fact, the rest of the Bible is the explanation of God‘s plan to restore mankind to his original dominion, and two enthrone himself as the king, over all the universe. What this means is that mankind is Gods agent in this dimensionality, and God has a limited himself to human activity as the primary agency within this dimensionality. Therefore, the spiritual beings that inhabit the other dimensions, that wish to utilise this dimensionality as a tool to overthrow the reign, and rule of God, must use human agents also. This is the reason that God became the man Jesus Christ. Now God himself could act within this dimension. Having returned to the heavenly realms, the church now is the body of Christ and displays his glory and enacts his will in this dimension.
Prior to this, Israel was God’s primary agent in the world, and was intended to be the path way of blessing for all mankind, but did not realise the fullness of her mission.
Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come.
2 Corintians 5:17
Christians now exist in two realms in this current dimensionality, but also in the new dimensionality of the new creation. There is an inherent tension that the Christian experiences because of this. This current dimensionality is subject to corruption, and we, therefore see suffering and evil and pain and death as a result. the apostle Paul, in his letters to the Romans reminds us of the entire universe, weights with groanings for the revelation of the new creation, as expressed in the sons of God.
Romans 8:19-21
For the creation waits with eager longing for the revealing of the sons of God. For the creation was subjected to futility, not willingly, but because of him who subjected it, in hope that the creation itself will be set free from its bondage to corruption and obtain the freedom of the glory of the children of God.
Ephesians 3:8-11
To me, though I am the very least of all the saints, this grace was given, to preach to the Gentiles the unsearchable riches of Christ, and to bring to light for everyone what is the plan of the mystery hidden for ages in God, who created all things, so that through the church the manifold wisdom of God might now be made known to the rulers and authorities in the heavenly places. This was according to the eternal purpose that he has realized in Christ Jesus our Lord,
What we are experiencing now as Christians is the result of Gods eternal plan to reveal himself to those creatures who inhabit the other dimensions. This who have rebelled against him and those who have not. We get to choose which side of the war we want to be on. The side that wins ultimately and experiences glory and honour and power in the new creation, or the side that experiences defeat and destruction forever.
It’s time to choose.
