So what exactly are you asking?
Most believers do know of the war in Heaven and the war that is still being fought for our very souls........Satan had been a more favored Angel until he had become prideful of himself and wanted to be worshiped above God, and some of the angels did follow him. These were the ones God had cast down, because God is the Alpha and the Omega and the only one to be worshiped. And this is the basis of the fight between Good and Evil (God and Satan) Here on earth and while we are alive in it, Satan is trying to deceive believers into following him instead of God. Our battle is against his lies and to not fall victim to them, but stand firm in our belief.
God wants to be reconciled to all of His children thru Faith and that is Heaven...... to be with Him. And without Him is hell.
In the beginning, it was perfect. Man (Adam & Eve) were innocent and were 'with' God in the Garden of Eden that was a Holy Place. (this was before Satan and his angels fall) Then Satan had deceived them, and they had eaten of the forbidden fruit of the tree of knowledge of Good & Evil that set all of mankind on a different path and separate from God. And the further away man became, the less direct interaction between man & God......and today there is little to no obvious sign of God........but as believers we see He is still there with us to encourage us to hold steady to our faith, all the while living in the world and constantly being tempted away. And in truth, the war has already been won thru the death and resurrection of Jesus Christ. His blood was shed to cleanse us from our sins that separate us from God. But while still on earth, we are still fighting the battles.
We know the end is near and that we are living in those last days when Satans time is coming to a close........seen by the measure of evil in the world that has increased 1000 fold in just our own lifetime
Only if you are any measure of a believer will any of that^^^ make any sense. And if it doesn't, then you might want to brush up on your Bible, and get right with God because the clock is ticking at an ever faster pace.
