6This man, Jesus the Messiah, is the one who came by water and blood—not with water only, but with water and with blood. The Spirit is the one who verifies this, because the Spirit is the truth.
10The person who believes in the Son of God believes this testimony personally. The person who does not believe God has made him a liar by not believing the testimony that he has given about his Son.
16If anyone sees his brother committing a sin that does not lead to death, he should pray that God would give him life. This applies to those who commit sins that do not lead to death. There is a sin that leads to death. I am not telling you to pray about that.
20We also know that the Son of God has come and has given us understanding so that we may know the true God. We are in union with the one who is true, his Son Jesus the Messiah, who is the true God and eternal life.
