CORE Christianity answers any and all questions about the Bible, theology, and matters of religion.

Hosted by Adriel Sanchez, CORE Christianity exists to strengthen the faith of believers and help them understand what it means to be a follower of Christ, and to reach those who have tragically left their faith behind. Their message of hope encourages us to look up and to raise our eyes to the triune God who has rescued us.
