You've put a new song in my mouth It is a hymn of praise to You Justice and mercy are its theme And I will live it back to You The kind of fast You've chosen, Lord It must reach out To broken lives and to the poor So change me, Lord I know You are the orphan's hope I know You are the widow's song O Lord, You're showing me what's on Your heart You've put a new song in my mouth It is a hymn of praise to You It's a hymn of praise Justice and mercy are its theme Justice and mercy And I will live it back to You Lord, I won't bring an empty song It's meaningless Without compassion in my life and holiness You're Father where no father lives And to the lonely You're a Friend O Lord, You're showing me what's on Your heart What is on Your heart You've put a new song in my mouth It is a hymn of praise to You It is to You Justice and mercy are its theme Justice and mercy And I will live it back to You Live it back to You I know You are the orphan's hope, I know You are the widow's song You're Father where no father lives, and to the lonely You're a Friend O Lord, You're showing me what's on Your heart You're a Friend Let justice roll like a river Let mercy flow to the needy Oh You're showing me what's on Your heart You've put a new song in my mouth It is a hymn of praise to You Justice and mercy are its theme And I will live it back to You Let justice roll like a river Let mercy flow to the needy This is our song This is the choir Where You go, we will go, we will go Because we love You, Lord
