The fact is that you will not work for the transformation of society if you don’t believe society can be transformed. You will not try to build a Christian civilization if you do not believe that a Christian civilization is possible.
It was the utter confidence in the victory of the Christian faith that gave courage to the early missionaries, who fearlessly strode into the farthest reaches of pagan Europe as if they were at the head of an army, preaching the gospel, driving out demons, smashing idols, converting whole kingdoms, bringing vast multitudes to their knees at the feet of Christ. They knew they would win.
They could give up their lives in the struggle, certain that history was on their side, that Satan’s domains were being shattered daily, his illegitimate hold weakening and slipping with every advance of the Christian forces. They were not in the least bit pessimistic about the power of the gospel. God honored their faith in His promises, and enabled them to lay the groundwork for a Christendom which will someday embrace the entire world.
