This seems to be supported by passages in scripture like in John where it says that man prefers the darkness over light. This implies that man will always choose darkness if left on his own. It is only by the intervention of God in leading us to faith that we can possibly do otherwise. This seems to make sense to me. Decisions are made by weighing options.
People make decisions based on available facts.
I'm thinking that the choices we do make are determined by many things. Conversely, if at lunch time your friend cancelled, you were not all that hungry, you still had more work to do, you could take lunch later etc. Different factors present different choices. This is exactly why God influences us to do good, because without an influence there is no reaction. It is for this very reason that thee is evil.
