“By this shall all men know that ye are my disciples, if ye have love one to another.”
King James Version (KJV)
13:33 Ye cannot come - Not yet; being not yet ripe for it. #John 7:34|.
13:34 A new commandment - Not new in itself; but new in the school of Christ: for he had never before taught it them expressly. Likewise new, as to the degree of it, as I have loved you.
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.
Joh 13:35 By this shall all [men] know that ye are my disciples. The love and self-sacrifice of Christians has done more to extend the name of Christ than argument. In the early ages, heathen were wont to say: "See how these Christians love one another".
