Imagine a cup.
Now, a pitcher of water set beside it. Pour the water in the cup. When the cup is full, don’t stop pouring. Is the cup getting any more full? No. The cup is your spirit. The water is truth. Your spirit may be filled with truth at varying levels, even entirely. Yet truth may not be fully comprehended by our form. There are many spiritual practices which point to the truth. I believe the Bible is the practical guide on how to excel spiritually. It teaches love, character, and positive psychology.
