My reply is primarily about Church growth and the importance of fellowship.
Wherever you go, don't imagine this sentiment is American/Western only as many have claimed/alluded.
If Christ doesn't change you nothing really has changed.
Proselytizing by active action and being examples by our (different/changed post conversion) behaviour are duties of everyone in Christ. As is fellowship.
As exemplified by those who do it in countries and areas where it might mean death like where I live today.
"Take up your cross and follow me" indeed.
