Mike Bickle emphasizes the prophetic call to build the house of prayer as illustrated in Haggai's messages to the Israelites in 520 BC. He draws parallels between their struggles and the challenges faced by modern houses of prayer, urging believers to recognize the significance of their work in the context of God's eternal purpose. Bickle highlights the importance of perseverance, spiritual resolve, and the understanding that their efforts contribute to a greater divine narrative that connects past, present, and future worship sanctuaries. He encourages the community to see beyond immediate challenges and to embrace the calling to create a place of continuous worship and prayer.
