10 Whoever believes in the Son of God accepts this testimony. Whoever does not believe God has made him out to be a liar, because they have not believed the testimony God has given about his Son.
11 And this is the testimony: God has given us eternal life, and this life is in his Son.
12 Whoever has the Son has life; whoever does not have the Son of God does not have life.
