1 John 4:2-3 NIV
2 This is how you can recognize the Spirit of God: Every spirit that acknowledges that Jesus Christ has come in the flesh is from God,
3 but every spirit that does not acknowledge Jesus is not from God. This is the spirit of the antichrist, which you have heard is coming and even now is already in the world.
1 John 4:13-17 NIV
13 This is how we know that we live in him and he in us: He has given us of his Spirit. 14 And we have seen and testify that the Father has sent his Son to be the Savior of the world.
15 If anyone acknowledges that Jesus is the Son of God, God lives in them and they in God. 16 And so we know and rely on the love God has for us.
God is love. Whoever lives in love lives in God, and God in them.
17 This is how love is made complete among us so that we will have confidence on the day of judgment: In this world we are like Jesus.
1 John 5:4-5 NIV
4 for everyone born of God overcomes the world. This is the victory that has overcome the world, even our faith.
5 Who is it that overcomes the world? Only the one who believes that Jesus is the Son of God.
