What does the Bible say about God's unchanging purpose?

God's purposes are constant and irrevocable, rooted in His sovereignty and righteousness. Zechariah 6 portrays God's plan through the imagery of brass mountains that symbolize His unmovable decree. Romans 8:28 explicitly states that 'all things work together for good to them that love God, to them who are the called according to his purpose,' affirming that nothing can frustrate God's ultimate goal for His people. Additionally, God's counsel stands forever, confirming that every event in life is orchestrated to fulfill His divine plan. This assurance calms the fears of believers, reminding them that God's will leads to triumph over adversity.
