Israel in the New Testament

What role did Israel play in God's purposes during the time that the Lord Jesus Christ was on earth? What role did Israel play in the days following Christ's ascension into heaven, i.e. the time covered by the Acts of the Apostles? What role did Israel play after that? Do they have any role today? The authors of this publication have sought to give clear and concise answers to the above and similar question, believing that an understanding of the place of Israel in the New Testament helps Christians in their interpretation and application of the Scriptures.
