Mark 9:18
So, we have the same thing over in Matthew chapter 17, and yet the language regarding the demon is not included. Instead, the man is describing the antics of his lunatic son. So we ask why the difference?
It seems likely that this man at first told the disciples his son was a lunatic. But, upon the arrival of Christ, the Lord asks some questions and makes some statements that cause the man to communicate the whole truth.
Some might try to separate these two instances, claiming there a different event, but that’s just not possible. The circumstances of the case are too similar to be different events. No, the similarities we have here are due to the fact that the lunatic claim was the first story.
Heavenly Father, may we always be truthful with you! You know what is inside us. You know our hearts. You alone may read our minds. May you always find there praise for you, and not anything else. Your name is truly great, and worthy of all praise! You are faithful, and wise, and true, and loving to the end. You are worthy of our service. In the name of the Lord Jesus Christ I pray and praise You, Amen.
