The problem with religious groups and churches is that there is always the tendency to quote single verses without the context which explains what the whole thing is about. If you need more love, ask for it from God. You can not learn to drive a car without actually starting to do that. You can think about this at home, for you remember how you normally act. In all likelihood your fellowship is dictated by the standards of this world.
Birds like to be with birds of like feather.
People tend to talk with people with approximately the same status in society as themselves, they prefer to talk with people with the same colour on their skin as they themselves have, or with people who are of the same cultural background as they. People prefer to talk with people who are as rich, or richer, than they themselves, but not with those who are poorer. Singles talk with singles and not with families with kids, adults talk with adults and ignore the children and the youth. And so on. And then the rest of the Bible.
