John 1:12-13 - But as many as received Him (Jesus), to them He gave the right to become children of God, to those who believe in His name: who were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.

***For one to be saved, he must accept Jesus Christ as Lord and Savior, taking God at His prophetic word, believing Jesus is His son. Upon doing so, he receives the Holy Spirit and experiences being born again, making him an heir of God's kingdom, granting him eternal life, which begins in that moment.
