It sums up why Jesus came to earth, to die for the sins of mankind. It tells us that God is love and not willing that any should perish, but that all should come to repentance. When we receive Christ as Savior we pass from death, separation from God, to life eternal, when we die we will be with the Lord in heaven. Those who have the son has life, those who do not have the Son of God has not life. Verily, verily, I say unto you, he that heareth my word, and believeth on Him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life. John 5:24
