This book takes a look at the Kingdom of God - what it meant to the Jewish people of Jesus' time and earlier - and what it meant to the early Christian Church and later. The differences between the Kingdom and the Church; and the similarities between the two are pointed out and discussed. It should be no surprise to anyone who claims to be a Christian that the present-day Church is in trouble; and that God is calling out for it to return to Him - to return to that place called the Kingdom of God. In this book, we consider what the Church once was, what it is today; and what it must become before the Return of the Lord. As Paul the apostle said, It must be a "glorious church, not having spot, or wrinkle, or any such thing;" and we, as the Church, must prepare to meet our God.
