Is God Unfair or Unjust?

The apostle paul is indignant in romans chapter nine when that kind of argument comes before him. It's as if paul does what jesus does, and worships god because who he is and his the rightness of him doing as he pleases. When i meet this objection that god is unfair or unjust to choose some and not others, i try to remind people that no, it would be just to condemn a sou that's right to judge ur. And through him, and to him are all things amen.
