When Rainbows Preach! Genesis 9:13The sermon explores the biblical significance of the rainbow, contrasting its original meaning as a covenantal sign of God's mercy and faithfulness after the flood with its contemporary appropriation as a symbol of human pride and social agendas. It emphasizes that the rainbow preaches God's judgment upon sin, the restraint of His wrath, and the enduring nature of His covenant with humanity, ultimately pointing to the Lord Jesus Christ as the ultimate ark of salvation and urging listeners to anchor their faith in His promises rather than worldly symbols.
