Living in the light of Christ’s return is the duty of every generation of Christians. But, as Christ’s parable in Matthew 25:1-13 warns us, all face the danger of falling asleep on watch. R B Kuiper’s sermons reprinted here were preached after the First World War and intended to help Christians live in readiness for Christ’s coming. Here is a timely reminder that wars and disasters point to the onward march of the purposes of God and bring us ever nearer to the great consummation of all Christian hopes.
