Even when things in my life are hard, I know God is with me. I feel his presence through the people at my church who pray for me and support me. I see him in the Christian friends he's given me. I try to serve him by counseling at a Bible camp in the summers. And I still hear his voice through his Word and through his answers to my prayers.
So why do I believe in Jesus? Because he's real. That night in the library, when I hit the bottom, my New Age thinking didn't help me. Buddha wasn't there for me.
It was Jesus who saved me.
