If your child denies that you exist, I think it would be wise to take him to a good child psychiatrist. If you clothed, fed, and educated him, and even gave him his own room, taught him right from wrong, loved him and nurtured him, and he denied that you exist, he certainly needs evaluation or he's just plain rebellious to a point of being really weird. Either way, you should make that trip to the psychiatrist.
Your alluding to God sending His children to Hell is a typical mistake often made by those who profess to be atheists. God never sends His children to Hell. All of them will go to Heaven. However, children of the devil will go to Hell, and that's what the Bible clearly says we are until our sins are forgiven, and we are born into the family of God.
The things that comes so naturally to us—lust, pride, greed, anger, hatred, selfishness, ingratitude, etc., are not attributes of God, but are from the god of this world. Jesus said that he is our father and it's his will we readily do.
The second big mistake atheists make is that they trivialize both sin and God's righteousness. They see little wrong with greed, hatred, lying, anger, lust, pride, envy, ingratitude, stealing, adultery, or the killing of a baby in the womb. This is because until we come to Christ, we are "ignorant" of God’s righteousness. How true that is. We have no idea of what "holiness," or "perfect righteousness" are, but that's what we must face on Judgment Day.
If you lift your hand to strike your dog, there probably won't be any repercussions. Try and hit a police officer and you may go to jail. Try and hit a judge, and you will go to prison. But if you lift your hand to strike the President of the United States, and you will probably be shot before you even get a hand to him.
It's the same crime, but each one has a different punishment, depending on the status of the one whom the crime is against.
Every time you sin, in thought, word, or in deed, you are sinning against a morally prefect and holy God, and at the same time you are "storing up wrath" that will be revealed on Judgment Day. If God gives you justice, you will be damned. You have fair warning, and you may repent and be forgiven because of what Jesus did on the cross.
He took the wrath of the Law of God upon Himself, so that your case could be dismissed. You can be forgiven every sin you have ever committed, if you trust alone in Jesus Christ who died for sinners and rose again on the third day. You are not a child. You are a grown human being, so please give this some mature thought.
