John Rankin is president of the Theological Education Institute (TEI) International. He grew up in an agnostic Unitarian context before he ran into the presence of the living God, and converted to a biblical and evangelical faith in 1967. He holds graduate degrees in theology from Gordon-Conwell and Harvard, and is ordained through the Vineyard Christian Fellowship. He is also founder of the Mars Hill Forum series, through which he engages leading skeptics, unbelievers and others, on theological and political topics. The goal is not to win an argument, but to win a relationship, apart from which the Gospel will not be advanced. He and his wife were married in 1977 and have four grown children.
