" . . . You must not hide yourself."
If you are like me, sometimes you probably feel like you would like to be invisible, or anonymous. You would like to have your own private (and "perfect") life, separated from the pedestrian problems of the masses. But God would not have us live like that. Instead, He would have us be involved in the troubles, trials, and misfortunes of other human beings--some of whom are churchmen, and others of whom are not.
The Deut. 22 passage (above) is in a context of the believer not ignoring the lost possessions of one's neighbor. Instead of "looking the other way," or overlooking these things, we are to get actively involved. Christ did this for us, His church; and we are to follow His pattern in His (sovereignly-guided) world today.
