That's true, but I guess it really doesn't matter what the level of technology is or the pressures of leadership. After all, Adam and Eve sinned in a perfect environment with only temptation from the serpent and each other. But the pressures are greater for those who must set an example, and the Bible tells us the standards are higher, so it really is a tough job. We are all weak but that points out all the more our need for a Savior and Helper. Why anyone could look at all this and still say we have to try and earn our way to heaven, I don't know. But when we do fall, we know God will forgive us if we repent.
