I would go as far to say that there are 200 million bad angels. That means 400 million good ones.
Why the exact fraction of 1/3.
Can you imagine any circumstance in which an exact fraction of people broke off from a group that large?
If you believe God is SOVEREIGN, and we do, then we must realize that He has been, is and always will be in control. He allows evil for a purpose.
He put the Tree of Knowledge Of Good and Evil in the Garden. Evil already existed. He knew Lucifer would fall and exactly how many angels would follow. He allowed Satan into the Garden for a purpose.
The knowledge of good could not really be known or appreciated without knowing evil. It was all part of His plan.
People have been taught and believe that this was an accident ... or God took a chance, hoping for the best ... come on.
We know love, mercy, forgiveness, faith, goodness, joy, hope, trust, and patience because we have experienced and learned what it is like to be without these attributes. We know Jesus, who came to die so that we may live. We know death so that we can know life
I would say God purposed for all of it to happen.
He set it up so that when Lucifer found out that God was going to create a universe, earth with all kts beauty and givebit to man, whobwas to be made in His image, that he would love him, that man would allowed to procreate, multiply and fill the earth with his offspring and to top it off, the angels were to watch over us and serve us too ... wow, Lucifer and 1/3 of the angels went ballistic. He must have made him and exactly 1/3 of the angels specifically with this pride that when challenged would rebel, insite jealous envy and hate ... evil. OR He just released that precise amount from their attachment and loyalty to Him for His purpose IN ORDER to follow Lucifer who became Satan.
Doesn't it also seem odd that Satan cannot do anything unless he has God's permission? Has that ever happened in history with our enemies? Do they ask permission before they can kill, pillage and plunder? People, mobs and nations don't ask permission before they war but the real war is in the spiritual realm behind the scenes and these wars must be ordained by God before they are enacted.
Even what appears to be the smallest insignificant battle between just two people happens under His watch. He knows when a sparrow falls so how much more does He love us. This will ruffle some feathers out there ... so let it be.
