John 9:41 Jesus said, “If you were blind, you would not be guilty of sin; but now that you claim you can see, your guilt remains.
Imagine you were walking along and stepped in some paint; when you continued to walk, you would be spreading the paint where you walked and you would know to stop and clean up.
But, if you were blind, you may not know you have stepped in paint, and you would not know you were spreading it everywhere!
God has allowed us to hear the gospel so we can know what is right and wrong – we don’t have the excuse of “we didn’t know it” anymore!
