The one who believes in the Son of God )has the testimony in himself; the one who does not believe God has made Him a liar, because he has not believed in the testimony that God has given concerning His Son.
11And the testimony is this, that God has given us eternal life, and this life is in His Son.
12He who has the Son has the life; he who does not have the Son of God does not have the life.
This Is Written That You May Know
13These 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.
14This is the confidence which we have before Him, that, if we ask anything according to His will, He hears us.
15And if we know that He hears us in whatever we ask, we know that we have the requests which we have asked from Him.
