Joe Granieri presents four keys to hearing God's voice, emphasizing that this ability is accessible to all Christians, regardless of spiritual maturity. The method involves stilling one's mind, cultivating vision by focusing on Jesus, expressing gratitude to God, and then allowing spontaneous thoughts to flow and be recorded, a practice Joe refers to as journaling. He contrasts left-brain (logical) and right-brain (intuitive, imaginative) thinking, asserting that hearing God's voice often engages the right brain through imagery and intuition. Joe also highlights the importance of believing in God's absolute goodness and draws parallels between this process and the prophetic visions of biblical figures, underscoring that God desires intimate communion with His followers, similar to His original intent in the Garden of Eden.
