Jesus is here talking about his apostles going to others. Does this mean: "He who you force yourself upon, will have me force myself upon them, and he who has me force myself upon them is forced upon by him who sent me." ???
This passage is speaking of the RECEPTIVITY of those the apostles preach to. If they permit the apostles, then they are permitting our trinitarian God entrance as well. "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 sup with him and he with me."
Matthew 18:5 - "And whoever receives one such child in My name receives Me;
The notion that the child is forcing itself on the apostles is misguided. The verse is about RECEPTIVITY, i.e, volitional permitting of the child into one's world.
It is entirely clear that the word "receive" has a volitional element to the extent that one could almost use the word "permit" as a synonym.
Interestingly, elabov, the greek, has the basic thrust of "take."
