Do most of what you do out of selfish ambition or vain conceit, and seriously, do not consider others better than yourselves. Each of you should look to your own interests. Others will figure it out in due time.
Or Romans 14...
Shun contact with fellow believers who don't see things the way you do. And jump all over them every time they do or say something you don't agree with—in particular when it seems that they are strong on opinions but weak in the faith department. Remember, you have a religious institution to protect. Treat them harshly.
Or Colossians 4:5-6...
Be ungracious in the way you act toward outsiders; make the most of every opportunity. Let your conversation be always full of truth, seasoned with harshness, so that everyone has the answers to the questions you want them to ask.
Well, what do you think? Is it the responsibility of the un-churched to adapt to our sub-culture or is it the responsibility of the mature believer/church to adapt to the un-churched? Sometimes we get it backwards don't we? All we really have to do is seek him first and then all the other stuff will be given us.
