G-d is unchanging. It’s right there in Torah. He even tells you not to put your trust in the "son of man" in whom there is no salvation.
Yet Jesus is called "son of man" 88 times in the Christian bible!
Matthew uses the term 32 times
Luke uses the term 25 times
John uses it 12 times
Yet the T'nach (the "OT" - "only testament") tells us: "Do not trust in princes, or in the son of man, who has no salvation." (Psalm / T'hillim 146:3).
Could it be any clearer???
If you need a few more:
"I HaShem do not change ." Malachai 3:6
"Before Me no god was formed, nor will there be one after Me. I, even I, am HaShem, and besides Me there is no Savior.” Isaiah 43:11
“I am the first and I am the last; apart from Me there is no G-d! Isaiah 44:6
"I am HaShem, and there is no other; besides Me there is no G-d" Isaiah 45:5
"Remember the first things of old, that I am G-d and there is no other; I am G-d and there is none like Me." Isaiah 46:9.
A little math for missionaries. . . 100% + 100% + 100% does not equal 1 no matter how many Trinitarians tell you that it does!
Sophiee Saguy has been countering false missionary claims about Judaism and the T'nach (Jewish bible) for nearly twenty years. You may find her on FaceBook and at the Messiah Truth forum.
