George Warnock emphasizes the invitation from God to dwell in His presence, as expressed in Isaiah 57:15. He encourages believers to not just visit God occasionally, like the disciples, but to make a continuous commitment to walk with Him daily. The sermon highlights that true understanding of where God dwells comes from personal experience and relationship, rather than mere knowledge from others. Warnock calls for a humble and contrite spirit, which is essential for revival and connection with the Holy One. Ultimately, he urges listeners to accept God's invitation to 'Come and See' for themselves.
