Don't equate peacemaking with peace-achieving. A peacemaker longs for peace, and works for peace, and sacrifices for peace. But the attainment of peace may not come. Romans 12:18 is very important at this point. Therefore Paul says, 'If possible, so far as it depends upon you, live peaceably with all.” That is the goal of a peacemaker: “If possible, so far as it depends on you...” Don't let the rupture in the relationship be your fault.
