"I'm a sinner. I fall incredibly short of the glory of God. We all do. I gave my life to the Lord in fifth grade, and it's the most important decision I've ever made and everything I do incorporates Jesus Christ."On college campuses, he often took questions from skeptics about the evidence for the Bible and why he believed Christianity was true while sharing its impact on his life.At a campus event in April, Kirk defended Christianity as a positive force in America."The mechanisms of a religious society is good for everybody. When somebody walks around and thinks that you were created and that you're not God, you tend to have better citizens," he said.During another debate with an atheist earlier this year, he pointed to the hope Christianity offers of an afterlife."I would argue you have a lot more faith than I do. You have a lot more blind faith to believe that everything around you, love, joy, peace, sadness is all just a construct of neurons firing in your brainWe as Christians have hope that we are going to see our loved ones again and that we will be in heaven and that we will be in perfect peace and that this is not it. In fact, there's something even better awaiting us."CHARLIE KIRK LEAVES BEHIND POWERFUL CHRISTIAN FAITH LEGACY AFTER TRAGIC SHOOTING"Jesus is honestly the most important thing," Kirk told Fox News last month while discussing NFL quarterback Lamar Jackson resharing his faith-based post.Kirk said at the time that he believed the nation was in the midst of a spiritual revival."We are seeing Gen-Z go back to church in record numbers. We are seeing a Christian revival that should give everyone in this audience hope. It's the greatest news happening in America right now," he said.CHARLIE KIRK ROSE TO BECOME CONSERVATIVE POWERHOUSE, TRANSFORMATIVE CAMPUS FIGUREOn Wednesday, Kirk was fatally shot while speaking in front of thousands of students on the Utah Valley University campus.
