The Bible tells us that all believers have a new identity in Christ. What does that actually mean?

In Christ’s resurrection a new age came into existence! Why do Christians need to orient their whole selves around this new reality?

Why is it that no one can inherit eternal life without being regenerated by the Holy Spirit, and why is this truth a comfort for believers?

Some hear Jesus’ teaching and love it, and their lives are transformed for the better by it. Others hear it only reluctantly and remain diamond-hard against it. What makes the difference?

Does it seem to you, as it does to me, that it has become more common for our public debates to be framed as being between the “good guys” and the “bad guys”? The people on “our side” are perceived as “good,” and the people on the “other side” as “evil.” What does the Bible have to say about how we view each other?
