You’re calling all humans children of the devil. Not even Jesus did that; He reserved that curse only for certain people.
You are putting words in my mouth which I never said. We are all born into sin, and until we confess those sins, repent and serve the Lord, we are children of the devil. Jesus had some very strong words for some people, but I’m not referring to children who are innocent or those with diminished capacity who may not know better. I do not judge those - only God can.
