Their Master's Voice

Of the five books that make up the Major Prophets in the Old Testament, three are amongst the largest of the Bible: Isaiah, Jeremiah, and Ezekiel. As if to underscore their Major status, each one is significantly longer than the Minor Prophets combined. Although the specific details of each prophet's contribution differ, a more general overarching theme may be discerned in them all: to remind their respective target audiences of their covenantal obligations. The prevailing human condition throughout the ages ensures that, while circumstances, cultural development, and technological advancements do change with time, the underlying sinful disposition of mankind remains constant in every epoch. Mercifully, God's messages to both victim and perpetrator alike are similarly unchanging.
In the stream of progressive revelation, it would be irresponsible simply to dip into the waters of the Old Testament and translate its lessons to our day without due process. That process might include asking certain questions of the texts under consideration. Are the lessons provided by these Old Testament saints applicable to us as Christians in the twenty-first century? Do their words still speak today? Only if Christian believers are still prone to such folly as chasing disposable pleasures instead of choosing meaningful pursuits.
