Here's a video where Greg Koukl and Deepak Chopra discuss the meaning of faith. Click the link to see the streaming video. (6:22 long)

Chopra seems to love saying what people want to hear rather than saying things that actually make sense. Is sin merely ignorance as Dr Chopra says? That seems ridiculous. Certainly if a person truly isn't aware that what they are doing is immoral then we cannot blame them for what they are doing. But that is not what sin is. Sin is when people do things they know are wrong … and if we are honest with ourselves we know that we sin all the time.

On the topic of sin, Ray Comfort and Kirk Cameron encourage an evangelism style that confronts people with the Ten Commandments. They ask people if they've broken the Ten Commandments, and then when people inevitably admit that yes, of course they have, then therefore they are "sinners" in need of forgiveness. While true in a sense, a non-Christian could easily simply deny the Ten Commandments and their argument falls apart. After all if a person doesn't believe the Bible is the word of God, why should they give credence to the Ten Commandments? However, IMHO it's totally unnecessary to bring the Ten Commandments into the argument, and it works just as well without even mentioning them. Here's why:

Regardless of whether a person is Christian or not, everyone has their own moral standards; aka their moral conscience, or moral rules. And whether a person accepts God's moral rules or not, every person must admit that they have broken THEIR OWN moral rules.

The question then becomes: Who do you think has higher standards when it comes to morals … you or God? If you say God has higher standards, then we're in a heap of trouble, because we've already admitted that even by our own standards we don't measure up, so that means we fall WAY short of God's own standards, whatever they may be. If someone were foolish enough to claim that we have higher standards than God, then they would be claiming that we have greater (more just, more accurate) moral standards than the God who is the source of all moral standards, which is absurd.

Greg makes a great comment near the end of the video regarding "guilt", which is also made in an article on Greg's website:

Folks, we don't get rid of guilt through denial . We get rid of guilt through forgiveness. And that forgiveness can only come from the One whom we have offended. The One who gave the law in the first place. (Read Greg's full article here.)
