I think the problem is we all make the same mistake the jew's made. We look to the law. And we say, Well I do not commit these sins, or I do not do those things which are unlawful. So i must be a pretty righteous person.
I see it differently, my friend.
The Jews, just like the whole world in Noah’s days, were sinning. They were not looking to the law.
All people on earth have the ability to stop sinning. What they did not have is the ability to say, “I have made my heart clean, I am pure from my sin” (Proverbs 20:9).
Nothing before Christ’s sacrifice could “purify a peculiar people, zealous of good works” (Titus 2:14) so all people, including Daniel, Isaiah, etc., could never claim to be nothing but guilty of having sinned with their fathers.
Now that we have the perfect sacrifice in Christ, we should walk worthy of that perfect sacrifice (Hebrews 10:14; Ephesians 4:1).
Matthew 5:48
Be ye therefore perfect, even as your Father which is in heaven is perfect.
