You know, it used to be that American culture in general understood that we're sinful, but not anymore. Which is why teaching the gospel, starting in Genesis, is important. Sin entered into the world through Adam, as described in Genesis. The problem is that we have Christian leaders compromising God's clear Word in Genesis with evolution, millions of years, or both. If we cannot trust what God says in Genesis, we cannot trust the gospel. Sadly, years of such compromise has greatly weakened the church to now allow for increasing open attacks on those who teach the gospel. Those attacking the gospel are intent on imposing their religion of atheism on this generation of kids.
