JPL, thanks for that, I'll take a look.
Greenworm, here's my best shot to answer your question about the fallen angels and the Bible sections.
May the Lord forgive me for minimizing His Word but if I could humbly break it into key parts, here they are.
1) The Creation - a perfect world with no death, no sin, no suffering and no sorrow. Mankind had intimacy with God.
2) The Separation - when man broke God's only commandment in the Garden, it caused a separation, spiritual death to mankind, and a corrupted world, separated from God. Also, Satan (out of pride and envy of God - Isaiah 14:12-14) rebelled with his angels (Revelation 12:9) and as a result, they currently rule this world as deceivers. God promises a redeemer would come and the penalty for sin is death. Satan and his angels knew God intimiately so they have no second chance, whereas God loves us and knows we are separated. Thankfully, He has given us a grace period even though we are sinners.
3) The Promise - God choses a people (the Israelites) to inherit the promised land but their rebellion and disobedience leads to them ultimately rejecting their true Messiah, Jesus. God then allows the Gentiles to be a part of the promise through Jesus. The sacrificial system, the freedom from captivity in Egypt, the Passover, the forty years in the desert, the bronze serpent in the desert, the water and the rock, Abraham/Isaac etc. The whole Old Testament is a foreshadowing of Jesus Christ and the seriousness of sin to our Holy God.
4) The Saviour - Jesus Christ, being Word of God made flesh, humbles Himself, comes into the world, lives a sinless life, and dies to pay our fine on the cross. He rises from the dead and defeats death. He now sits at the right hand of God the Father.
5) The Offer - The Gospel (Good News) is that God offers a full pardon to all who repent and trust in Jesus for salvation. That's God's mechanism to save people from the penalty He must bring down upon their sins. The New Testament explains how Christians should live, fight the spiritual battles we face in this world, and share the Good News with others as all who die in sin with face God's eternal wrath.
6) The Restoration - Jesus will return after a horrible final seven years to this world. Revelation 13 says Satan and the Beast (Antichrist) will be worshipped by the whole world. Imagine the wicked deception behind this. God will then pour out His wrath on this final rebellion and a New Heavens and New Earth await all who are redeemed with Christ. Jesus, being God with us will rule forever. Death will be no more, animals will no longer kill each other, sin will be gone and it will never end.
As for Satan, he's very real but to no surprise this is probably what the majority of the world thinks of Satan.
Nothing could be farther from the truth. Google Sanat Kumara or the Ascended Masters for one of his wicked deceptions.
