To say that “no one locks their doors here” is a badge of honor for many communities. It is an expression of confidence in the safety of the neighborhood. I once lived in such a community. When my parents first moved there, there was not even a lock on the door! Today I always lock our doors before going to bed. I bet you do too. I don’t think there is anything wrong with locking the door to your house but is worthwhile to consider whether you are locking danger out or locking yourself in.
For Jesus’ disciples, it was a little of both.
