So he'll be there with each of you individually.. but 'in the midst of you all' is a different story
Church also not meaning a building but the members of a church gathered to resolve a sin issue
Ecclesiastes 4:12
And if one prevail against him, two shall withstand him; and a threefold cord is not quickly broken.
That is talking about two people “Christians” being and working together; but what makes that 3 fold cord? It is Jesus.
Matthew 18:19&20
19Again I say unto you, That if two of you shall agree on earth as touching any thing that they shall ask, it shall be done for them of my Father which is in heaven.
20For where two or three are gathered together in my name, there am I in the midst of them.
Verses 19&20 are not taken out of context. Verses 16-18 are talking about what to do if a brother or sisters wrongs you. Here is the 2 passages together . Notice there is a space between 18 and 19. The end of one paragraph and the start of another.
15Moreover if thy brother shall trespass against thee, go and tell him his fault between thee and him alone: if he shall hear thee, thou hast gained thy brother.
16But if he will not hear
thee, then take with thee one or two more, that in the mouth of two or three witnesses every word may be established.
17And if he shall neglect to hear them, tell
it unto the church: but if he neglect to hear the church, let him be unto thee as an heathen man and a publican.
18Verily I say unto you, Whatsoever ye shall bind on earth shall be bound in heaven: and whatsoever ye shall loose on earth shall be loosed in heaven.
19Again I say unto you, That if two of you shall agree on earth as touching any thing that they shall ask, it shall be done for them of my Father which is in heaven.
20For where two or three are gathered together in my name, there am I in the midst of them.
Here it is in the Berean Study bible notice it is under a whole different heading
A Brother Who Sins
(Deuteronomy 19:15–21)
15If your brother sins against you,
c go and confront him privately. If he listens to you, you have won your brother over.
16But if he will not listen, take one or two others along, so that ‘every matter may be established by the testimony of two or three witnesses.’
d 17If he refuses to listen to them, tell it to the church. And if he refuses to listen even to the church, regard him as you would a pagan or a tax collector.
18Truly I tell you, whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.
Ask in My Name
(John 16:23–33)
19Again, I tell you truly that if two of you on the earth agree about anything you ask for, it will be done for you by My Father in heaven.
20For where two or three gather together in My name, there am I with them.”
Again please show me where you are getting this idea from. It makes no sense to me
