217. [verse 20] 'Behold I stand at the door (janua) and knock' signifies that the Lord is present with every one in the Word, and draws nigh there to be received, and teaches how [this may come to pass]. [Words] similar to these are said by the Lord in Luke:-
You shall be like unto men who wait for their Lord, when He is going no return from the wedding, so that when He comes and knocks, they may open to Him immediately Luke xii 36.
That a 'door' signifies admission and entrance may be seen above (n. 176).
