Started with Adam and Eve. God said “do not eat of the tree of knowledge of good and evil”. Eve was tempted by the serpent and she gave to Adam and they both did eat. The serpent convinced them if they ate they would be like God themselves (hmm another lie, imagine).The Angel drove them from the garden and said that man will work by the sweat of his brow and women will give birth in gr8 pain. Adam and Eve’s disobidience to God is what brought evil into the world. And, yes he wants you to excercise freewill to love and serve him, He does not want a bunch of mindless robots. Even the Angels have freewill. When satan was cast out of heaven he was given dominion as the prince and power of the air here on earth. but, he has no influence over christians because we are commanded by our God to occupy until His return. When God created the earth the tectonic plates were cogent but, since the original sin things have kind’a gone down hill. And besides the shaking and trembling becomes very importantduring the tribulation.
