God's election is sovereign.

And for the record: jw and mormons are not Christian.

So which of the 10's of thousands of Christian denominations are Christians?

Christians are defined by believing this creed:

Yeshua was born with life in His spirit, of a virgin and therefore into a body capable of sin but did not sin.  He was judged and suffered in hell for our sins and then was raised from the dead back into that same body now glorified.  And if He walked righteous in His body that was capable of sin then we should walk righteous in our bodys that are capable of sin because if one believes this creed in their heart and calls on Yeshua they will have the same life in their spirit as He does in His (Not in His divinity but in His humanity).

Anything short of the above is not a Christian.
jws and mormons (and many others) cannot say that above creed (not without repenting or hardening their heart anyway).

(THIS CANT BE CONSIDERED PROSELYTIZING, I WAS JUST ANSWERING YOUR QUESTION.)
