1 John 5:11-14

And the testimony is this, that God has given us eternal life, and this life is in His Son. He who has the Son has the life; he who does not have the Son of God does not have the life. These things I have written to you who believe in the name of the Son of God, so that you may know that you have eternal life. This is the confidence which we have before Him, that, if we ask anything according to His will, He hears us.
