First of all you start on a wrong foot. There was never an Adam and Eve. Man has been around for at least 200,000 years. According to the Bible the universe was built in 6 literal days.
There is no contradiction if you don't need faith (and/or works) but you were predestined to be saved before the world began? And even worse, because you were not predestined, you will end up in hell? What kind of justice is this in a religion?
Talking of being saved which of the three is valid?
1) Rom 2:13 "For it is not the hearers of the law who are righteous before God, but the doers of the law who will be justified."
2) Gal 2:16 "(We) who know that a person is not justified by works of the law but through faith in Jesus Christ"
Eph 2:8-9 "“For it is by grace you have been saved, through faith, and this is not from yourselves, it is the gift of God not by works, so that no one can boast.”
3) James 2:14 "What good is it, my brothers, if someone says he has faith but does not have works? Can that faith save him?...24 You see that a person is justified by works and not by faith alone....26 For as the body apart from the spirit is dead, so also faith apart from works is dead."
