Salvation begins with an experience of new birth apart from natural birth into the world. According to the Bible, all humanity has descended from Adam and Eve who were created sinless and perfect by God from the dust of the earth (Genesis 1 :26, 27 ; 2:7). Though brought into existence for fellowship with God, they were given the agency of free will to make personal choices in the newly created world.
At some point this faculty was tested by Satan in a temptation to eat fruit from the forbidden tree of knowledge of good and evil–a temptation that was failed and which changed the nature of humanity forever (Genesis 3:1-20). Because of this failure, the nature of sin was inbred to the offspring of the first family throughout the succeeding generations. This resulted in an innate tendency to rebel against the will of God (Romans 5:12).
In his first letter to the Corinthian Church, the Apostle Paul mentions that the solution to this sin problem, and its penalty is through the remedy of Christ’s sin offering at Calvary and His subsequent resurrection (1 Corinthians 15:21, 22). It is through the death ,burial and resurrection of Christ that fallen humanity rediscovers and experiences the life lost by disobedience of our ancestors in the garden of Eden–a spiritual rebirth.
This born again experience cannot be achieved through an intellectual process, as was clearly explained by Jesus to Nicodemus (John 3:1-18), but through another kind based upon belief in Jesus Christ as the Son of God and faith in His crucifixion and resurrection as being enough for redemption and confession of personal sin. This Salvation of the soul begins with a decided repentance from sin but is consummated by works of the spirit in the life of the individual–justification and regeneration. being born again depends not only upon faith of the person seeking salvation, but also upon the works of grace in the heart by the Holy Ghost.
