Sam Devis is a former Christian and produces a podcast called When Belief Dies. One of the triggers for his faith deconstruction was reading Yuval Noah Harari’s ‘Sapiens’ and the consequent questions this raised, particularly around evolution. Andrew Halestrap is emeritus professor of biochemistry and senior research fellow at Bristol University and was previously the national chair of Christians in Science. They join Justin to discuss faith, proof and the relationship between science and God.
