Hello Psalm40.17:
Romans 8:28-30 prove that only certain ones are elect:
"And we know that for those who love God all things work together for good, for those who are called according to his purpose. For those whom he foreknew he also predestined to be conformed to the image of his Son, in order that he might be the firstborn among many brothers. And those whom he predestined he also called, and those whom he called he also justified, and those whom he justified he also glorified. " (Romans 8:28-30, ESV)
Clearly, a simple read of this passage shows that ALL those whom are predestined will be glorified. Since not all are glorified, then not all are elect to life.
By definition, "elect" means choosing some out of others.
And, by the way, Calvin didn't originate this believe, the apostles did, as did Christ. Read John 6 - the whole chapter. Do a search on "elect" or "chosen" in the new testament. It is a wonderful doctrine that maginifies the grace of God and minimizes fallen man.
And, remember, God is not unfair if He chooses to give to some what He is not obligated to give at all. That is what grace and mercy are!
