6And Jesus Christ was revealed as God’s Son by his baptism in water and by shedding his blood on the cross —not by water only, but by water and blood. And the Spirit, who is truth, confirms it with his testimony.
10All who believe in the Son of God know in their hearts that this testimony is true. Those who don’t believe this are actually calling God a liar because they don’t believe what God has testified about his Son.
16If you see a fellow believer sinning in a way that does not lead to death, you should pray, and God will give that person life. But there is a sin that leads to death, and I am not saying you should pray for those who commit it.
20And we know that the Son of God has come, and he has given us understanding so that we can know the true God. And now we live in fellowship with the true God because we live in fellowship with his Son, Jesus Christ. He is the only true God, and he is eternal life.
