A.W. Tozer emphasizes the radical changes in the contemporary world and challenges the notion that the Bible must be reinterpreted in light of these changes. He asserts that God remains unchanging and that the truths of Scripture, including miracles, are still relevant and valid. Tozer calls for courage among believers to stand firm in their faith and resist societal pressures to conform or dismiss biblical truths. He encourages Christians to be steadfast in their beliefs, asserting that true faith will ultimately influence the world rather than the other way around.
