"The Four Great Covenants " shows the Biblical basis of the close connection between Christianity and Israel, and how the work of Jesus is rooted in the promises to Israel. This book is one of the clearest explanations of the roots of Christianity in the Covenants God made with Israel. Christianity is shown as the flowering of God's promises to Israel rather than a replacement of them. 'The Tabernacle of David" is a remarkable explanation of how the restoration of Israel today and the flowering of Christianity world-wide are dynamically intertwined. The connection between the presnt-day restoration of Israel and the present day restoration of the power of the Book of Acts was foretold by the prophets.
