Unfortunately, the Bible disagrees with you. You can't get there based on merit or simply being a "good person". There's only one way, and that's through Jesus Christ.
Point is, what's a "good person", and by whose standards are you judging their "goodness"? If you say "God's standards", then you have to accept what He says sin is, and what the criteria are for eternal life with Him. If you say "man's standards", then, well, none of us have a chance because we all can make the argument that we live "good" lives. To man, "good" is a relative term.
I'm not surprised by the research in this article. It just goes to show that the born-again parents probably aren't true converts in the first place. Any honest, truly regenerated person would first see to their own family before preaching to the rest of society. A true convert knows that they are seperate from society, and would raise their kids accordingly. A true convert would know what God's position is on child-rearing and would obey without a second thought.
This research shows the dangers in man-centered, "name it and claim it", emotionally-driven 'conversion experiences' as opposed to honest, humble, sincere callings.
Oh, you meant Gods definition...
...One that doesn't have a flexible acceptable level of evil.
