Blind Leading the Blind, Having Eyesight Problems and Finding the Good Guide

The bible says we will be guided. We all need a guide. When we go to places where we have never been, we need a guide to help us get there. Do they know the trail? Will they take the correct fork in the river? Do they have experience with the terrain?
In the bible there are blind guides. They lead their followers into a pit.

Leave them; they are blind guides. If the blind lead the blind, both will fall into a pit. (Matthew 15:14)

Both teachers and taught are alike ignorant of the truth. The people had no spiritual light, and, applying to their appointed pastors, they learned nothing profitable from them; for these were as much in the dark as themselves. (Pulpit Commentary)

Jamieson-Fausset-Brown Bible Commentary says

"Let them alone: they be blind leaders of the blind. And if the blind lead the blind, both shall fall into the ditch—Striking expression of the ruinous effects of erroneous teaching!"

Those who guide this people mislead them, and those who are guided are led astray. And those who are guided by them are brought to confusion. (Isaiah 9:16)
But God sends His Spirit to guide us into all truth.
When the Spirit of truth comes, he will guide you into all the truth, for he will not speak on his own authority, but whatever he hears he will speak, and he will declare to you the things that are to come. (John 16:13)
Gills Exposition again,

He is as a guide, he goes before, leads the way, removes obstructions, opens the understanding, makes things plain and clear, teaches to profit, and leads in the way men should go, without turning to the right hand or left, which, without such a guide, they would be apt to do.

Yes, we do go astray, don't we. It is grace abounding that we have a guide. Though we are no longer blind, we do have eyesight problems. Though we are saved by grace we still dwell in our flesh. The flesh obscures the full vision of truth. Our desires, our sins, our temptations all cloud our vision. The Spirit is there to guide us into all truth. He sees perfectly and He knows the way. He illuminates the bible for us, Thy word is a lamp unto my feet, and a light unto my path. (Psalm 119:5)
Praise the Lord we have a guide who will draw us along the path, until finally, FINALLY, at the glorification, we can fully see. Our guide will be Jesus in the flesh, with us and never leaving us.
Until then, follow the bright, holy, pure Guide: The Spirit of Truth. His path leads upward. The paths of the blind guides only lead downward, into a pit.

The blind leading the blind. The pit awaits them and their followers
