What we have seen and heard we declare to you so that you, too, can have fellowship with us. Now this fellowship of ours is with the Father and with his Son, Jesus, the Messiah.

This is how we can be sure that we have come to know him: if we continually keep his commandments.

But whoever continually keeps his commandments is the kind of person in whom God's love has truly been perfected. This is how we can be sure that we are in union with God:

Whoever has earthly possessions and notices a brother in need and yet withholds his compassion from him, how can the love of God be present in him?

The person who keeps his commandments abides in God, and God abides in him. This is how we can be sure that he remains in us: he has given us his Spirit.

This is how you can recognize God's Spirit: Every spirit who acknowledges that Jesus the Messiah has become human and remains so is from God.

We have seen for ourselves and can testify that the Father has sent his Son to be the Savior of the world.

And if we know that he listens to our requests, we can be sure that we have what we ask him for.
