How to convert Christians to atheists in 30 seconds (ironically, using bible)

[Tonus]

But if one group has it ALL right, that doesn't mean that everyone else has it ALL wrong. It's not all or nothing. Some people have most things right, but are missing other things. Some have most things wrong, even if they have some things right. As I've said several times already: The bare minimum is that you live your life according to the truth and goodness that you know and are honestly trying to know more about. God can work with that. He can work with anything if that disposition is at the center of your life.

If there is agreement on details here and there --but no unified understanding of the person being worshiped-- that can also be a case of people blindly flinging darts at a wall. You may get clusters of darts here and there, but that just means that people looking in the same direction will naturally come up with a few similar ideas. We're talking about a being who appeared to people in more than one form and performed works of pure magic so that they had no other choice than to know he was real and that he was more than just another person. Then he is gone and humanity can't figure out who he is anymore.

3) Yes. Perhaps few people care to grow in the knowledge of truth and goodness?

Does that really seem to be the case? I've known a lot of religious people in my life, and I can't recall many of them who did not consider truth and goodness to be important. Most people strike me as being sincere in their religious belief and in their desire to be considered a good person. If few of them are finding the gate that leads to life, it's not out of a lack of desire. The instructions are not very useful.

4) While I would not accept the suggestion that god wrote people off, you ask a good question. This is what I would say. What-god-wants is for his creatures to come to the fullness of what they are. God's will for people's life, therefore, is expressed and evident in what-humanity-is. Just by being human, you express to others that God made people to achieve full-humanity through their own actions. In other words, since being fully-human means to become human-goodness, your own humanity is a sign of what-god-wants, i.e. eternal life of goodness.

I'm fine with these explanations, but they seem to go beyond what the Bible explains. Are there ways to know for certain that god wishes for us to come to our fullness, as opposed to expecting only a few of us to find the path to life? The latter would square with the old testament god who separated out a small tribe and used it to visit judgment on other tribes, only showing mercy to one tribe that offered itself up as servants. Could this not be an example of what God has in mind for the future, where he sets aside a very small group and accepts them as his nation, then leaves the rest to suffering and destruction?
