As humans we all have times of uncertainty and doubt about our beliefs. CS Lewis says faith is holding to what you once reasoned to be true even when you mood has changed rather than a blind leap into what you cannot understand.
Here’s a clip of Pro. John Lennox explaining rational Christian beliefs. He’s a mathematician at Oxford university whom I will be learning from this year at OCCA (Oxford Center of Christian Apologetics). If we use Occam’s Razor when we look at empirical evidence as we begin to create our worldviews then we’d be less likely to go around the block to cross the street. The problem is we have forgotten or we’re never trained properly on how to think correctly. Listen to how simply Pro. Lennox rejects poor thinking with reason and logic.
