When we assume our own personal or cultural applications are the same as the biblical principle (sometimes we even do this in the name of fighting relativity), we tend to trample on Christian liberty and fight about the wrong things.

We don’t like to be motivated by fear, at least not in our relationship with Jesus. Fear sounds too much like duty. We want to be motivated by love and do things because of delight. Granted, this is also biblical (2 Corinthians 5:14). But being motivated by fear is also biblical, and human.
Here was a group of men, a group very diverse in terms of age, background, personality, and gifting. And yet they worked well together, appreciated their differences, and even celebrated them.
