When a doctor tells you something can’t be reversed, restored or healed. (What I’m about to say, may stir up some controversy, sadly from the body of Christ).
When a doctor gives you that report, without realizing what he is saying, has given you a death sentence. He’s spoke words of death about you.
Prov 18:21 says:
Death and life are in the power of the tongue, And those who love it will eat its fruit.
Even though someone does not profess to be a follower of Christ, this passage of scripture remains true. So, how do you counteract the words of death spoken over you? Your faith in what the Word says and thanksgiving about that Word from Yahweh that was spoken to you.
Doctors can only give a report based on what they’ve been taught and what they’ve witnessed and observed in the natural. Truth (the Word) supersedes the natural. You don’t have to accept the report. You may have make some adjustments to your lifestyle related to your health situation, but you don’t have to accept a doctor’s report over what the Word says. Your Heavenly Father has the final say.
