Sin (disobedience) clouds our vision and interferes with our hearing.
"Son of man, you are living among a rebellious people. They have eyes to see but do not see and ears to hear but do not hear, for they are a rebellious people.”
“For this people's heart has become calloused; they hardly hear with their ears, and they have closed their eyes. Otherwise they might see with their eyes, hear with their ears, understand with their hearts and turn,
and I would heal them.'”
“But blessed are your eyes because they see,
and your ears because they hear.”
Sin clogs our ears like wax.
We must daily cleanse it out if we want to hear clearly.
