According to Christianity, the only thing that God requires of someone to be saved is for him to put his faith and trust in Jesus Christ, claiming His death as the acceptable payment for his sins. A person must recognize who he is before God and trust in the work of Jesus Christ. Because of sin and imperfection, people are separated from God and on the path to death.
In Christian belief, God does not want to leave people on the destructive path, so He made a way to be saved. Because of His great love and mercy, God allowed His son, Jesus Christ, to pay the price for sin. The Bible says that the penalty of sin is eternal death and separation from God. Christianity teaches that Jesus left Heaven and came to the world as a man and that He lived His entire life without sin. At the end of His life, Jesus was falsely accused and died a criminal's death in order to take on the sin of the entire world. Christians believe that Jesus was the ultimate sacrifice and bridged the gap between man and God. To prove His sacrifice and that He was the son of God, He defeated death by rising from the dead three days later.
