In his book Worship, John MacArthur describes the fallout of the biblical illiteracy that permeates the church today:

“Worship” aims to be as casual and as relaxed as possible, reflecting an easy familiarity with God unbefitting His transcendent majesty. This type of “worship” seems to aim chiefly at making sinners comfortable with the idea of God—purging from our thoughts anything like fear, trembling, reverence, or profound biblical truth. . . .

The decline of true worship in evangelical churches is a troubling sign. It reflects a depreciation of God and a sinful apathy toward His truth among the people of God. Evangelicals have been playing a kind of pop-culture trivial pursuit for decades, and as a result, the evangelical movement has all but lost sight of the glory and grandeur of the One we worship.  – John MacArthur, Worship (Chicago: Moody Publishers, 2012), 10-12.
