Truth is Not Found Easily
Your "knockout argument" is rarely a knockout argument.
That Christian debater on YouTube didn't destroy the atheist.
The silver bullets we seek often turn out to be Nerf.
The truth is rarely found easily. It's a grind.
It's hard work that, in the end, often feels obvious. Like you should have known all along.
But don't let that feeling make you look down on others who haven't made it through the process. And don't let it cause the future you to become lazy when in search of truth.
