1 John 4:13-15 NLT

And God has given us his Spirit as proof that we live in him and he in us. Furthermore, we have seen with our own eyes and now testify that the Father sent his Son to be the Savior of the world. All who confess that Jesus is the Son of God have God living in them, and they live in God. (1 John 4:13-15 NLT)
