Salvation of the World

Did Christ come to save this world? Or are we talking about a completely different world? Didn’t Christ call us out of this evil world? Is this world being judged today? And if not, when will this be the case? Could this be related to the resurrections? And why does the Bible speak of the resurrection of the just and of the unjust, as well as the resurrection to everlasting life, to judgment and to everlasting contempt or condemnation?
