 According to John, how do we know if someone is not a believer? They don't look like Jesus. He said, if you run ahead and you do not continue in the teachings of the Christ, you do not have God. You never have him. Go back to chapter two. If you continue in the teaching, this is called the doctrine of the perseverance of the saints. It's a clear evidence that, you know, Jesus works or the way we live is not how we earn salvation, but it is evidence of salvation.
