Passage
Ye call me Master and Lord: and ye say well; for so I am.
Ye call me Master and Lord: and ye say well; for so I am.
John 13:11 For he knew who should betray him; therefore said he, Ye are not all clean.
John 13:12 So after he had washed their feet, and had taken his garments, and was set down again, he said unto them, Know ye what I have done to you?
John 13:13 Ye call me Master and Lord: and ye say well; for so I am.
John 13:14 If I then, your Lord and Master, have washed your feet; ye also ought to wash one another’s feet.
John 13:15 For I have given you an example, that ye should do as I have done to you.
The verse centers on "call", "master", "lord", and "well". It is saying that the verse draws attention to "call" and "master", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 12's "So after he had washed their feet..." into verse 14's "If I then your Lord and Master...", so "call" and "master" belong inside that flow. In John context, the local focus is the identity of Jesus, new birth, eternal life, and belief and unbelief.
A plain takeaway is to answer the verse's own emphasis on "call" and "master" with trust shaped by these words, not by a vague optimism outside the passage.
