By the previous discoveries of danger, misery, and helplessness, and desert of wrath, the heart is prepared to embrace a discovery of mercy. When the soul stands trembling at the brink of the pit, and despairs of any help from itself, it is prepared joyfully to receive tidings of deliverance. If God is pleased at such a time to make the soul hear his still small voice, his call to himself and to a Saviour, the soul is prepared to give it a joyful reception.
