While closely linked, deeds of mercy and compassion are not the same thing as Gospel Justice. Gospel Justice moves us beyond deeds of mercy and compassion towards advocacy for those who have no voice/agency to do so themselves. Christian churches must work for justice and peace in their city, nation, and globally even as they call individuals to conversion and the new birth. Indifference to the marginalized and disadvantaged means there has not been a true grasp of our salvation by sheer grace.
He has shown you, O mortal, what is good. And what does the Lord require of you? To act justly and to love mercy and to walk humbly with your God. Micah 6:8
