The sin nature cannot submit to God, nor please Him, nor know the truths of scripture, so limited freedom!
You mistakenly equate the original sin of all mankind and the loss of man's free will. While we all must make this journey to earth, each of us has the "free will" to decide things for ourselves during the journey. No person is "pre-destined" for a particular thing to happen. The only thing that is "pre-destined" is birth and then death, and whether one makes it to, and then stays in heaven, is all up to the individual. We are given numerous chances to amend our sinful ways and forgiveness is always available. In the end the choice is ours, we are not subject to some pre - determined outcome.
