If the Blind Lead the Blind

Blind guidance ends in ruin.

Jesus warns that spiritual blindness is contagious: unseeing leaders and followers fall together, so discernment is necessary.

Scripture

Matthew 15:14

14 Let them alone: they be blind leaders of the blind. And if the blind lead the blind, both shall fall into the ditch.

Luke 6:39

39 And he spake a parable unto them, Can the blind lead the blind? shall they not both fall into the ditch?
