Your son is just as bad a sinner as you are and is in need of Christ just as much as you, and you should be ashamed of yourself for trying to make excuses for him rather than trying to share the goodnews of Christ.
What a foolish statement. Tell me, what sin has my son commit at eight months? Do you even KNOW what sin is? Let me help you out a little...
1 John 3:4 Everyone who commits sin also breaks the law; sin is the breaking of law.
Romans 7:7 What should we say then? Is the law sin? Absolutely not! On the contrary, I would not have known sin if it were not for the law. For example, I would not have known what it is to covet if the law had not said, You shall not covet.
