1 John 5:10-13 "The believer in the Son of God possesses the witness within himself. He who disbelieves God, makes Him out to be a liar, because he has not believed in the evidence God has given regarding His Son. He who has the Son has that life; he who does not have the Son of God does not have that life. I am writing this to you who believe in the name of God's Son in order that you may know that you have eternal life."
John 5:24 "Truely I assure you that he who listens to My message and believes Him who sent Me has eternal life; he comes under no sentence but has passed over from death into life."
