We must be bruised.
Not bruised so as to injure us, but bruised so as to lead us to forsake our sin and cling to our Savior. Bruising that may be as painful as any invasive medical procedure, but that which is needed for our healing. Bruising not only at the hands of the Lord, but bruising from our own hands as we humble ourselves under His mighty hand.
The plague of sin which inflicts us requires severe remedies, leading to bruising and pain but resulting in our healing. Yet in the midst of the pain and the suffering we can "come boldly to the throne of grace" (Heb 4:16) and joyfully receive His peace and presence.
