Passage
You call me Master and Lord. And you say well: for so I am.
You call me Master and Lord. And you say well: for so I am.
John 13:11 For he knew who he was that would betray him; therefore he said: You are not all clean.
John 13:12 Then after he had washed their feet and taken his garments, being set down again, he said to them: Know you what I have done to you?
John 13:13 You call me Master and Lord. And you say well: for so I am.
John 13:14 If then I being your Lord and Master, have washed your feet; you also ought to wash one another's feet.
John 13:15 For I have given you an example, that as I have done to you, so you do also.
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 "Then after he had washed their feet..." into verse 14's "If then I being your Lord and...", 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.
