I want to explained the reason God divide and rearranged the Universe and put a new creation and Kingdom in the spiritual side of the Universe.
1-think of the old spiritual creation and universe as an open place with no walls inside dividing the spiritual universe only those of the fallen angels. Like the rulers, the authorities, the world powers, the evil forces of wickedness in the heavens, Ephesians 6:10, spiritual Babylon, Egypt, and the queen of heaven.
The pagan world human spirits is already under the dominion of these evil powers, Ephesians 2:1-2, and Colossians 4:3 and control of by the element forces in the spirit world, those in the secular world do not know that fallen angels have control over their mind and souls and spirits.
2-These are no safe heaven for the spirits and souls even if a person becomes a Christ, because they will still exposed to the works of the fallen angels and the elements forces of this world.
3- So God made a separation in the spiritual side of the Universe so that after a person from the secular world becomes a Christian they can escape from the spiritual corruptions that is in the old creation and find rest and peace in the new creation.
4-God was thinking about our interest and so was Jesus Christ because they know that we had spiritual strongmen and wicked spiritual powers over us, that we could not break free from them, without the blood of Jesus Christ, Jesus Christ became a Ransom for us, and also a gift offering on the altar in Heaven to atoned for the sins of Humanity.
5-For this reason we are urge to spiritually enter the kingdom of God Matthew 6:33 so that we can be free from demonic attacks, once our spirit-man enters the kingdom of God we will be find and we will also Grow with spiritual knowledge.
6-even though our body and soul is still in the old creation physically a Christian have to privilege to get set free from spiritual bondages from darkness and be liberated from Satan’s power, as a Christian God< Jesus Christ, and the Holy Spirit will give you spiritual power to walk in spiritual freedom in the spiritual world far above the heaven (the place that is in circled with the verse Revelation 21:10).
7-now people should not say that God does not love them, God, show His Love through Jesus Christ to all of us, but physically it is not possible to under spiritual things, with your physical intellect it is impossible to truly understand the Love of God for you and your soul, But when you become a spiritual person, God will give you a spiritual intellect and then you will start to understand God, Jesus Christ and the Holy Spirit.
8-every person must have Faith when they come to accept Jesus Christ as their Lord and Savior, this is like joining the Army if war brake out you have to go to war so it is with Christianity. We are all already in the enemies spiritual world, but God wants to get our spirit out of this old evil spiritual world, for us to learn this we have to become spiritual, God is a Spirit and He will teach us mysteries and give us revelations as spiritual knowledge all the days of our lives if we walk in His plans and WILL.
I hope these 8 points help you to understand the work of the Cross and the see that Jesus Christ and God, and the Holy Spirit is for you.
But the evil one is against you, in the Bible, the book of ACTS 26:15-18
