Pastor Tony Dettle teaches on Psalm 46, a powerful affirmation of trust and confidence in God's protection and presence. It begins by acknowledging God as a refuge and strength, an ever-present help in times of trouble. The psalmist encourages the reader to be still and know that God is in control, assuring them that even amidst chaos and upheaval, God's power and sovereignty will ultimately prevail, bringing peace and security to those who put their trust in Him.
