The song “Mercy Speaks” was extracted from the book of Romans 9:15 For he saith to Moses, I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion.
Kindly read further – Hebrew 4:16, Matthew 9:13, Ephesians 2:4-5, psalm 51:1-2, Micah 7:18 etc.
Mercy has to speak for any positive action to happen or take place.
By the rendition of this song, mercy will speak, glory and miracles will spring forth.
