Behold, I stand at the door, and knock:
if any man hear my voice, and open the door,
I will come in to him, and will sup with him, and he with me.
Revelation 3:20
"Why does He?
Not because He is without home elsewhere.
But He goes round from door to door in Laodicea.
He stands at each, and knocks,
because He came to seek and to save that which is lost,
because He cannot give up the purpose of communicating eternal life to as many as the Father hath given Him, and because He cannot become known to the inmate
unless the door be opened and a welcome given Him.
He knocks and knocks.
But you cannot receive company at present;
you are worn out with labor; you have wheeled round the sofa;
you are making yourself comfortable, and you send word you are engaged.
He knocks and knocks. . .
Oh, fatal worldliness!
The Lord of glory comes all the way from His celestial palace--
comes in poverty, in sweat, in blood--comes to the door of a professed friend,
who owes all to Him, and cannot get in!-- The word "if" implies that some will not hear.
Though He stands and knocks,
yet some will close their ears to His tender entreaties.
But it is not enough simply to hear. We must open the door."
Daniel & the Revelation p.401 Uriah Smith
