Ask a Mormon to just pay attention to how much Jesus is mentioned and of how much He is touched on in the Mormon Church as the weeks go by.

Then present this passage to them at some point.

"I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me. I do not nullify the grace of God; for if justification were through the law, then Christ died to no purpose" (Gal. 2.20,21). "For by grace are ye saved through faith; and that not of yourselves: it is the gift of God. Not of works, lest any man should boast." (Eph. 2.8,9). "All things were made by him [Jesus]; and without him was not any thing made that was made" (John 1.3) "who alone" (1 Tim. 6.16) was "from everlasting" (Neh. 9.5) with the Father and the Spirit. "He that believeth on him is not condemned: but he that believeth not is CONDEMNED ALREADY, because he hath not believed in the name of the only begotten Son of God" (John 3.16).
