By this we know that we remain in him and he in us, because he has given us of his Spirit.

He who believes in the Son of God has the testimony in himself. He 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.

If anyone sees his brother sinning a sin not leading to death, he shall ask, and God will give him life for those who sin not leading to death. There is a sin leading to death. I do not say that he should make a request concerning this.

We know that the Son of God has come, and has given us an understanding, that we know him who is true, and we are in him who is true, in his Son Jesus Christ. He is the true God and eternal life.
