Matthew 18:20 For where two or three are gathered together unto my name, there am I in the midst of them.
Matthew 18:21 Then Peter came to him and said, Lord, how often shall my brother sin against me and I forgive him? until seven times?
The verse centers on "again", "shall", "agree", "earth", "concerning", "matter", and "whatsoever". It is saying that the verse draws attention to "again" and "shall", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 18's "Verily I say to you Whatsoever ye..." into verse 20's "For where two or three are gathered...", so "again" and "shall" belong inside that flow. In Matthew context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "again" and "shall" with trust shaped by these words, not by a vague optimism outside the passage.
