Here's an exercise: read this site, then put into words just why you believe in Jesus Christ and in what the Bible says.

It's not immediately easy. I mean to do it honestly and deeply. My way of knowing I believe in Jesus Christ and in what the Bible says is the existence of the Kingdom of Satan, and of his followers, and their false idols (and of the low-level of influences and deadness and violence and chaos and corruption and overall soul-killing garbage of it). This I can see and experience and feel and know exists in a real way. Now, I had to go a negative route to see just why I believe in Jesus and what the Bible says, but atheists do force that at times. They force you to find something tangible you can look to and actually 'know'. The Kingdom of Satan I can actually know and observe.

But it's also faith itself that enables me to 'see' the Kingdom of Satan, and to see through its illusion and false idols, and to see the spiritual bondage and death in it all. Faith also enables me to see the truth in the Word of God and the Kingdom of God and then to sort everything into what's real and what is not real. Faith 'hath a piercing eye' to see into the spiritual realms, as a Puritan once said...
