How do we know God's purpose is specific to His elect?

God's purpose is not universal but particular to His elect. Romans 8:28 states that 'all things work together for good to them that love God, to them who are the called according to His purpose.' This highlights that God's workings are directed towards those He has called and predestined. Similarly, in Jeremiah 29:11, God speaks specifically to His chosen people, assuring them of thoughts of peace and an expected end. This exclusivity is rooted in God's sovereign will, which chooses whom to bless and save based on His eternal purpose, not on human merit.
