Art Katz emphasizes the critical role of the Baptism of the Holy Spirit in effectively reaching the Jewish community in the last days. He reflects on the early Church's reliance on the Spirit's power, as demonstrated in the Book of Acts, and challenges contemporary Christians to rekindle that fervor in prayer and outreach. Katz laments the current lack of urgency and depth in prayer among Spirit-filled believers, urging them to embrace the fullness of the Spirit to witness boldly to the Jewish people. He draws parallels between the early Church's experience and today's challenges, stressing that the same Spirit is necessary for impactful ministry. Ultimately, Katz calls for a return to the passionate intercession and bold proclamation that characterized the early believers.
