Only the gospel exposes the cancer of idolatry.

The trouble today is that many Christians live in a kind of bubble of assumptions about what their Christianity means, especially if it places them comfortably among "the good guys," - assumptions that are likely to be drawn as much from folk-Christianity, surrounding political culture, popular pulp-books about the "End Times," or their favourite guru writer or therapist, than from sober and comprehensive reading of the Bible as a whole. Prophets and preachers have the unwelcome task of pricking that bubble with the sharpness of actual texts and teachings of the Bible itself.

Yahweh demanded justice for the poor, compassion and equality for foreigners and refugees, systemic redress for poverty, structural mechanisms to protect the homeless and family-less from abuse and destitution, fair and equitable distribution of land, integrity in the judicial system, humility, simplicity and morality in the government (as opposed to wealth, women and weapons), etc. etc. If you want that kind of society, you need to be faithful to the living God.

Old Testament Israel had some foundational pillars of faith. They were true and robust and God given. The trouble was that people had come to trust in them merely by repeating them, without paying any attention to the ethical implications of what their faith should mean in how they lived. They believed God had given them their land. He had. But they had not lived in it in either gratitude or obedience. They had not fulfilled any of the conditions that Deuteronomy had made so clear.

We may legitimately see in the [Old Testament] event, or in the record of it, additional levels of significance in the light of the end of the story – i.e. in the light of Christ

It's important, though, that there are not "four gospels." There is only one gospel: the good news of what God has done through Christ to save the world. But we read that one gospel in four complementary accounts: The gospel, according to Matthew, according to Mark, according to Luke, according to John.

It is not so much the case that God has a mission for his church in the world, as that God has a church for his mission in the world. Mission was not made for the church; the church was made for mission - God’s mission.
