It is a humble request made to God in the midst of most disturbing and shattering moments. We ask God, then, according to His will, dependent upon Him, in our sickness, for health. We ask Him in serious illness of a child if it might be His will that the child be restored. We ask Him in the waywardness of a son or daughter or a loved one in the family that such a one be brought to repentance according to His gracious will. A supplication means that we feel a need pressing upon our heart and we bring a petition to God as those who have no strength.
