What is the ultimate truth?
It's not always what you can see. If you look at one foot and assume there are two or three, you'd be wrong. But if you only believe what you see and never believe what you don't see, you'd be wrong about the most important thing of all. The one thing you don't want to get wrong is knowing who God is, why you're here, and where you're going when your time on earth is done.
The spiritual reality transcends the physical.
