Jesus is real

GOD IS REALLY REAL FOR REAL

What is the truth? I can't keep saying I don't know. There has to be truth or everything is a lie. And how do I know that the truth is actually the truth? How do I know I'm not blindly believing a lie? I can't live with doubt in the truth. I don't want to just believe what I think is true, I want to know the actual truth and live it out with everything I've got. How do I find the truth? Where do I start?
