There are times when our children's sin really catches us by surprise. In our shock we ask how could he to do that; where did that come from? The hard truth is that your child began life as an enemy of God. He (or she) was an unregenerate, sinful, rebellious enemy of God. Do you believe this? If you do, you can have great hope and peace about your child and his relationship to God. If you don't believe this, then you will have no reason to tell your child what he needs to know to become God's friend.
Paul teaches in Romans that all have sinned and come short of God's glory (Romans 3:23) and that there isn't anybody who is righteous, not a single one (Romans 3:10). This is also what David says in Psalm 51:5, "Surely I was sinful at birth, sinful from the time my mother conceived me."
Paul sums this doctrine up in Ephesians 2:1–3:
And you were dead in your trespasses and sins, in which you formerly walked according to the course of this world, according to the prince of the power of the air, of the spirit that is now working in the sons of disobedience. Among them we too all formerly lived in the lusts of our flesh, indulging the desires of the flesh and of the mind, and were by nature children of wrath, even as the rest.
