Many people would answer that question with the word ‘yes’. Someone once said that faith is believing in something you know not to be true.
But this is terribly wrong. Faith is not proof, but it is believing because there is enough evidence on which to base a relationship of trust. The Christian apologist and theologian Alister McGrath (himself a former atheist scientist) has said that neither religion nor atheism can be proved, but the issue is which provides the best explanation of life.
The God: New Evidence project has put together various video series about the consistency of scientific evidence with belief in God, and the evidence in history for Jesus and the Resurrection. Have a look at their website here and see what you think.
