(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 testified concerning his Son.) ¹ 

Dear friends, do not believe every spirit, ¹  but test ²  the spirits ³  to determine ⁴  if they are from God, because many false prophets ⁵  have gone out into the world.

Now who is the person who has conquered the world except the one who believes that ¹  Jesus is the Son of God?

I have written these things ¹  to you who believe ²  in the name of the Son of God so that ³  you may know that you have eternal life.

Now ¹  this is his commandment: ²  that we believe in the name of his Son Jesus Christ and love one another, just as he gave ³  us the commandment.

Everyone who believes that Jesus is the Christ ¹  has been fathered ²  by God, and everyone who loves the father ³  loves the child fathered by him. ⁴ 

And we have come to know and to believe ¹  the love that God has in us. ²  God is love, and the one who resides ³  in love resides in God, and God resides in him.
