Ligonier Ministries is an international Christian education organization established in 1971 to equip Christians to articulate what they believe and why they believe it. Founded by theologian Dr. R.C. Sproul, proclaiming God's holiness is central to the ministry's purpose. To this end, the ministry produces the Renewing Your Mind radio broadcasts, The Reformation Study Bible (ESV), Tabletalk devotional magazine, new titles by Dr. Sproul and other contemporary authors and theologians through the Reformation Trust Publishing imprint, numerous teaching series, sacred music, national and regional conferences, and an extensive catalog with more than 3,000 unique resources.
