<p>13:6- see on Mt. 3:11.</p><p><i>But I hope you shall know that we have not failed the test</i>- Paul's hope as ever is for their repentance, through recognizing the Spirit of Christ within them and walking according to the Spirit. If they did that, as explained on :4 and :5, they would perceive that the same Spirit was within Paul, and he too had not failed the test but was legitimate.</p>
