Sometimes I will be asked my particular position on a doctrine, philosophy, or other teaching. Many times, I have an opinion. Sometimes I have merely guidance as to which questions to ask. Other times, I have no clue. I have often observed that theologians (and philosophers) will jump to a position within days (sometimes mere minutes) of learning that a particular question in theology exists! This is not necessary, and it's also dangerous. It's not necessary because we aren't called to have all the answers right away. Just as our spiritual growth and sanctification take time, so too our intellectual development will take time. It's dangerous because it fuels both a sense of pride/ego and the drive to defend something we really don't fully understand. Also, taking a position too early may blind one to the fact that he might not be asking the right question in the first place!
You don't have to take a position on everything immediately. In fact, there may be issues so non-essential and difficult that you don't ever take a position on them. And that's OK.
