Truth does not fear questioning and investigation. A well-founded faith can withstand people poking at the foundation. In fact, which speaks better of someone claiming to be on the side of truth: "Take my word for it," or "Ask me anything"?
Christians are often accused of blind faith-of believing in something without any reasonable or factual basis. And let's be honest: we often leave ourselves open to the charge because of how we talk about our faith and what we believe. We treat it as something that exists apart from the available evidence. We divorce our faith from the process of scientific inquiry since the loudest voices in science say the science leads elsewhere. And if that's how we treat it, why would we expect our accusers to be any more charitable?
Paul spoke of more than 500 who were witnesses to the resurrection (1 Cor. 15:6). He said most were still living at the time he wrote 1 Corinthians. The implication? You could ask them about the resurrection. Ask them about what they had seen. Are we willing to have what we believe subjected to the same scrutiny? Are we confident enough in the reason for our hope that we are willing to lay it out on the table for someone else to scrutinize?
