So if there was a battle in Heaven, then we can assume that there can actually be a negative thought in Heaven. This actually implies the we do in fact maintain our FREE will once we die. Why wouldn’t have lucifer have been purified before going into heaven and seeing the face of God?
God always existed onto Himself before Heaven and Earth and the rest of Creation were “created”. There is also a concept of paradise that is associated with Heaven but is not really fully “heaven” in the proper sense that we think of it.
So one of the prior posters had it correct. The Angles in the instant of their creation made the decision to serve God or reject God. But in that instant of creation none were yet in the full communion with God through the beatific vision and therefor were not really fully in “heaven proper” until the decision was made to be obedient to God in that one decisive instant. The Angels that rejected God essentially manifest and cast themselves into Hell in the same instant of their creation and rejection while
fully aware that they were doomed to eternal punishment. They deliberately chose eternal punishment over eternal service and purpose and fulfillment in and to God. Their pride and contempt is so profound that if God gave them the choice for mercy they would still reject mercy and stay in hell. In fact their very spiritual nature makes it impossible for them to have a reason to change their decision to reject God - it is their nature to be decisive and unchangeable. Those angels that fell became what we now call demons of hell and these consciously elected that state of existence rather than serve God for all eternity.
Most of us human beings can not fathom just how profoundly evil these demons are since we are bathed in God’s constant universal grace that beckons us toward salvation. We simply can’t comprehend that kind of evil while we experience the goodness of God’s love; a condition we irreverently and unthanfully take for granted. But a being that willfully cuts itself off fully from God’s grace (as in hell) loses all good that come from God’s grace and loathes its very existence and the existence of all other beings and especially good things that remind it of what it could have been.
The only reason that humans do not become utterly evil like the demons when we commit a grave sin is that while we have the grace of mortal life we still have an opportunity to repent while we are alive (due to God’s ever beckoning universal grace).
In essence we humans are in our “moment of creation” and are making our decisions for or against God just like all the angles did. But at the instant of human death and God’s final judgement those humans dieing impenitent in grave sin are cut off completely from God’s loving grace and become just like the fallen angels. Such become the offspring of Satan and are not of God. But those who put their trust in Jesus and obey Him and receive His graces and forgiveness through His Church become God’s children and will be permitted to enter the beatific vision after final purification if necessary.
The bottom line is that the disobedient Angles were not ever permitted to possess the full manifestation of heaven and were never permitted to commune with God in the Beatific Vision - they were only given an awareness or visions of it sufficient for them to decide their fate. Those angles that did not rebel were then permitted in the instant of their acceptance of God to have full access to heaven and the beatific vision. Therefor scripture is consistent - nothing impure may enter heaven.
