What does it mean to be a Christian?

Well Paul answered this way:

"You, however, are not in the flesh, but in the Spirit, if in fact the Spirit of God dwells in you."

So a Christian is a person in whom the Spirit of God dwells.

And as Paul wrote, "anyone who does not have the Spirit of Christ does not belong to Him."

So what does it mean to be a Christian?

It means that the Spirit of God lives in you.

And it is his presence in you that makes you new and different.

So let me ask, do you have the Spirit of God living in you?

If so, you are a Christian. You belong to Jesus.

And that's good news
