If we were to use a guide that did not know the territory it would be foolish. The guide is someone we should be able to trust.
What would happen if someone claimed to be a guide that could help us but they were not? They pretended to know the territory but only knew the territory that they had grown up in. Would we want them to be our guides?
In Matthew it says, “And if a blind man guides a blind man, both will fall into a pit” Matt 15:14 (NASU). Make sure you have the right guide.
