In words that might be addressed to so much of 21st century Western Evangelicalism, Ortlund Jr.comments on Old Testament Israel’s spiritual adultery as found in the book of Hosea,
The people failed to make meaningful connections between their theology, history and worship, on the one hand, and their real-life problems, on the other hand. They put God, his covenant, his power, his wisdom, into a limiting category of thought – they could not bring themselves really to believe the assurance of Deuteronomy 28:1-14 – while ‘the real world’ was another category altogether with its own rules and its own resources. They acted as though faith in Yahweh alone were an impracticable policy for life. As a result, they dishonoured him even as they thought they continued to honour him.
Moreover, unalloyed, classical Yahwism was losing its compelling power among the people. It was being redefined with fewer sharp edges and more open doors as a broadly inclusive religion, increasingly tolerant of elements of paganism.
