William Porter's book is an urgent call to be alert and to be faithful. He inspires us with the reality that God is in control of all things and that God can be trusted, even as the world seems to teeter on the brink of so much chaos. His careful and faithful exposition of Scripture points us to the reality that God will build his church and that we can be confident in the purposes and plans of God. As a result of this, we are inspired to be faithful. William reminds us that good eschatology is a motivation for faith, and for faithfulness. He reminds us that Christ will come for his bride, and that we, the Church Militant, can be confident, clear, courteous and courageous in our witness to Jesus, because one day we will join the Church Triumphant and we will reign and rule with our Saviour. This is a book about our times, for our times. It reminds us that we stand until the end of time and go to the ends of the earth proclaiming the eschaton, the gospel and the goodness of God.
