I only see what my eyes are equipped to see. The same is true when I look at you, when I look at the past or the future. The transcendent reality can only be perceived through faith. The Psalmist reminds us that walking without the perception of God, of reality, is dangerous. Now faith is the assurance of things hoped for, the conviction of things not seen.
Faith is the assurance more than the hope.
It is the assurance that only this sixth channel can transmit. The other five channels can be fooled by any five-channel transmitter. The sixth channel is the clear channel that only God can use. Whatever comes through it is reality. The rest is virtual reality.
