John Wesley on John 13:36

Peter saith, Lord, whither goest thou? - St. Peter seems to have thought, that Christ, being rejected by the Jews, would go to some other part of the earth to erect his throne, where he might reign without disturbance, according to the gross notions he had of Christ's kingdom. Thou canst not follow me now - But Peter would not believe him. And he did follow him, Joh 18:15. But it was afar off. And not without great loss.
