Condition: Dumbness

In Scripture, dumbness means inability to speak, not stupidity.

In Matthew 9:32-33, a spirit is responsible for a man’s dumbness.  When Jesus casts the devil out, the man is able to speak.

In Matthew 12:22, Jesus heals a dumb man who is also blind and deaf.  In this case, an evil spirit was responsible for the condition.

In Matthew 15:30-31, Jesus heals all who are dumb in a large crowd.  No demon is mentioned.

In Mark 7:32-37, a man who has a speech impediment is categorized as “dumb” even though he could apparently speak somewhat.  Jesus heals him.  No demon is mentioned as being involved.

In Mark 9:17-29, Jesus heals a boy who is dumb because of the working of an evil spirit.

In Luke 11:14, Jesus casts out a spirit, enabling a dumb person to speak.

In Isaiah 35:3-6,we see that Christ will take away dumbness when He comes to reign on the earth.  Where Jesus has His way, dumbness leaves.

There is one more instructive case concerning Zacharias, who was struck dumb, presumably so that he wouldn’t mess up the plan of God by speaking unbelief.  What’s interesting is that he was righteous before God as far as the Law went, but was still struck dumb because he did not believe.  This shows the importance that God attaches to faith.  You can be right morally, but you can’t please God without faith (Hebrews 11:6).

Luke 1:5-6:
There was in the days of Herod, the king of Judaea, a certain priest named Zacharias, of the course of Abia: and his wife was of the daughters of Aaron, and her name was Elisabeth.
And they were both righteous before God, walking in all the commandments and ordinances of the Lord blameless.

Luke 1:20:
And, behold, thou shalt be dumb, and not able to speak, until the day that these things shall be performed, because thou believest not my words, which shall be fulfilled in their season.

But of course, his dumbness DID get healed:

Luke 1:64:
And his mouth was opened immediately, and his tongue loosed, and he spake, and praised God.
