• Did Jesus offend Israel's religious leaders?
• What was Israel's leader’s response to Jesus' miracles?
• What were the "Traditions of the Elders"?
• What is the difference and significance of the terms "the Spirit upon" and "the Spirit in"?
• What's the significance of the stoning Stephen to death in Acts 7?
• What loss and what blessing came out of Israel's rejection of Christ?
• How was ancient Israel to learn of and Keep the Lord's Words in mind? How does this compare to that for the members of "the body of Christ" today?
• What is God's eternal plan for Israel and how does it differ from God's eternal plan for the members of "the church, which is Body of Christ"?
• What is the standing of individual Israelites today before God, and how is an Israelite to be saved today?
