Sorrow comes in various sizes and depth; but sorrow is a reality. The hung head of sorrow can be comforted by the One who knows what it is to weep.
Of course a hung head may be caused by shame. The same One who knows what it is to be tempted (and yet remain without sin) is willing to “lift our head” as we confess and repent.
When down, call upon the One who is more than able, more than willing, to “lift our head.”
