Yikes. That is complete and utter decimation of a perfectly good verse.He was blind. Being blind physically means he is unable to see physically. It's a picture of a spiritual reality.
And Jesus said unto him, Receive thy sight: thy faith hath saved thee.
Luke 18:42 KJV
"Thy Christ hath saved thee."
Luke 18:36 And hearing the multitude pass by, he asked what it meant.37 And they told him, that Jesus of Nazareth passeth by.38 And he cried, saying, Jesus, thou son of David, have mercy on me.
His physical blindness had nothing to do with his "spiritual reality", he relied on his hearing, which seems to be working just fine. Could it be you are reading something into the passage that just isnt there? And that the statement you made concerning miracles and inability is in error?
