King Ahaz of Judah learned the hard way that a refusal to stand and confess the truths revealed by the Lord leads only to disaster. Today, many professing evangelicals are repeating Ahaz’s error, diminishing the importance of difficult but crucial doctrines. But if the church is going to crash the gates of hell, she must reaffirm and recommit herself to the essential truths of the Christian faith, as Alistair Begg, James Boice, Sinclair Ferguson, John MacArthur, R.C. Sproul, and others remind us in Ligonier Ministries' 1997 National Conference, "Essential Truths of the Christian Faith."
