My advice: Read the Bible for what it is - the true word of God. Do not believe the gnostic / esoteric interpretations. They are Luciferian and lead to eternal damnation. According to a plain reading of the Bible, the fall of man was due to man's disobedience of God's command. We are not eternally doomed, as God has provided redemption through His Son Jesus Christ (God in the flesh). He died on the cross for our sins, then rose again from the dead. We must believe in His plan of redemption to receive the free gift of eternal life.
