One reading is 'my guest-chamber,' and that makes His claim even more emphatic; but apart from that, the language is strong in its expression of a right to this unknown man's 'upper room.' Mark the singular blending here, as in all His earthly life, of poverty and dignity—the lowliness of being obliged to a man for a room; the royal style, 'The Master saith.'
So even now there is the blending of the wonderful fact that He puts Himself in the position of needing anything from us, with the absolute authority which He claims over us and ours.
III. The answer and blessedness of the unknown disciple.
(a) Jesus knows disciples whom the other disciples know not.
This man was one of the of 'secret' disciples. There is no excuse for shrinking from confession of His name; but it is blessed to believe that His eye sees many a 'hidden one.' He recognises their faith, and gives them work to do. Add the striking thought that though this man's name is unrecorded by the Evangelist, it is known to Christ, was written in His heart, and, to use the prophetic image, 'was graven on the palms of His hands.'
(b) The true blessedness is to be ready for whatever calls He may make on us. These may sometimes be sudden and unlooked for. But the preparation for obeying the most sudden or exacting summons of His is to have our hearts in fellowship with Him.
(c) The blessedness of His coming into our hearts, and accepting our service.
How honoured that man felt then! how much more so as years went on! how most of all now!
Our greatest blessedness that He does come into the narrow room of our hearts: 'If any man open the door, I will sup with him.'
