I said something in my preaching class yesterday, and I want to preserve it here because it represents a key point in my learning process.
I've learned that for whatever is most important to me theologically, the opposite is just as important to someone else; and the harder I dig my heels in about being correct, the harder the other person will do the same. Sometimes it's important to back off--not on my convictions but on digging my heels in--and let time teach the lessons. If I really am correct, it will be apparent in time; and there really is no need to prove the point right this minute. In fact, sometimes in the process of giving grace to the other person, I learn a few things myself.
