Tim Keller has not given public support to Donald Trump or Hilary Clinton with the theologian telling Premier he prefers to keep politics out of his sermons.

Tim Keller is the founding pastor of Redeemer Presbyterian Church in New York City and became a New York Times bestseller through his books which include The Reason for God.
