<p>13:23 <i>But be warned, I have told you all things beforehand</i>- In place of the Olivet prophecy, John's gospel has the message about the Comforter. Through the gift of the Spirit, the Lord is present in our hearts with such reality that it is as if He were with us. All calls to go out and see Him here or there will therefore intuitively be found false by us. And the connection with the Comforter passages continues in this verse, with a clear link to Jn. 14:29: &quot;And now I have told you before it happens, so that when it happens, you may believe&quot;. The Lord was referring to the predictions of His sufferings and death; but here, the context is of the latter day tribulation. Those tribulations are to enable those who pass through them to fellowship with the sufferings and death of the Lord, that they might share in His immortality.</p><p>The intention of prophecy is that when it is fulfilled, then all is clear to the believers and they are thereby guided and strengthened. This will be particularly true in those last few days when the sign of the Son of Man is in the sky (Mt. 24:30), everyone somehow knows Christ is about to come- and inevitably false claimants will arise, perhaps one particular one will claim to be Christ and will go to battle against the real Christ. Hence the repetition of the Lord&rsquo;s warning about not being deceived by this person or related claims.</p>
