Art Katz emphasizes the necessity of the Holy Spirit's outpouring for the church to maintain its identity and purpose, warning that a church without a future becomes stagnant and fails to engage its members, especially the youth. He critiques the conventional church model that merely schedules services without fostering genuine community and spiritual growth, arguing that the church must embody the Kingdom of God now, rather than relegating its teachings to a distant future. Katz calls for a radical commitment to God's glory and a return to authentic Christian living that reflects the teachings of Jesus, particularly in loving one's enemies and embracing the cross. He warns against the complacency of modern Christianity, urging believers to seek a deeper relationship with God that transcends mere cultural Christianity. Ultimately, Katz challenges the church to recognize its role in God's eternal purposes, particularly concerning Israel and the coming age.
