Peace is the result of justification by faith. The person who relies on his works for justification can have no peace.
Charles Hodge (1797 – 1878) on Romans 5.1
If the world is little convinced that Jesus is God’s Son, it is due less to any apologetic deficiency and more to the disunity and dysfunction of our life together as the family of God. The Church’s failure in peacemaking is due in large measure to our failure as members to believe and appropriate the biblical truth that the Church is God’s family. Biblical peacemaking will only become firmly rooted in the Church when we recover the meaning and practice of the Church as the family of God.
Alfred Poirier, The Peacemaking Pastor (Grand Rapids: Baker, 2006), 91.
