I think to some degree it's impossible to disengage all personal preferences. We should be aware of when we are imposing personal perferences and be honest about it. I think we should also try not to do this.
We are not promised that we will all agree on everything (even the Gospels disagree on a few points). But we are commanded to love one another and to love this lost world. I know fellow believers who are very liberal and believe that the Bible is far less conservative in some areas. I might disagree, but I love them.
Say whaaaaaaaaaaaaa?
