King James Bible
"Even the mystery which hath been hid from ages and from generations, but now is made manifest to his saints:"
Paul refers to God's redemptive plan—particularly the inclusion of Gentiles through Christ—as a divine secret concealed throughout history. The double emphasis ('ages' and 'generations') underscores the lengthy hiddenness of this truth, which Old Testament believers could only glimpse in shadows and prophecies. The pivotal 'but now' marks the gospel age as the time of unveiling, when God openly reveals His mystery to believers ('saints'). This revelation comes through Christ's work and the apostolic preaching, transforming what was once hidden into accessible truth for all who belong to God.
