Every person will get the opportunity to come to the revelation and knowledge that Jesus Christ is Lord and Savior. If that person rejects that knowledge in this life, then he dies and comes before God, in the Presence of God He will know the truth. The bible says that God will call the past into account. He will show every man at what point in life they came to the knowledge that Jesus Christ is Lord and Savior. In addition, when you die and come before God in His Presence all truth is manifested. His holiness will be so great that men will automatically out of their own heart bow because of His greatness and confess that Jesus Christ is Lord and Savior.
