Our Lord said, "No man can serve two masters. For either he will hate the one, and love the other: or he will sustain the one, and despise the other. You cannot serve God and mammon." (Matthew 6:24)
And He also said, "Every kingdom divided against itself shall be made desolate: and every city or house divided against itself shall not stand." (Matthew 12:25)
Thus, one who was born a Jew and wants to convert to Christianity, must make the decision which master/house he will serve, and plant both of his feet there. instead of planting each foot in a different house, under a different master.
However, if this logic is not enough for you, I wrote an article a year and a half ago, using more Scripture to prove this case:

I also recently made a video using even more sources and logic to prove this case. Please choose whatever streaming service you wish to watch this video:

Christian faith comes from Jewish faith. What isn't is grassroots Christianity and modern American Christianity.
False. The Modern Jewish faith comes from the rejection of the Messias, Jesus Christ. Christianity is a fulfillment of the Old Testament Israelite Faith, which continues in the Church.
Old Testament Israelite Faith sums up as "if you disagree with me I am straight-up killing you". It's the exact same thing as "American Judaism".
American independent Christianity, the watered-down version preaches standard human decency.
That's not really true... The Old Testament Israelites only killed those spreading evil and degeneracy. Similarly, during the Middle Ages, the Church put down those same types of people... And rather reluctantly (the attempt was always made to convert and make several more attempts).
"American independent Christianity" promotes tolerance and complacency, which is why our society is falling to the forces of evil and degeneracy. You either destroy evil or it corrupts and destroys you...
I am referring to the side that didn't. Those who are literally calling for crusades against the current about to be world order. Those who regularly get purged by Communists from Soviet Russia and the Khmer Rouge as their spiritual leaders betrayed and abandoned them.
They literally invented ideological crimes that did not exist in Greece and Egypt, named the calendar over their savior, wrote all history books to paint everyone who opposes them as insane degenerates, invented Serfdom, indoctrinated people that they are born with original sin and deserve to die, starved billions of Europeans to death and refused to do anything during the Bubonic Plague and said that it is your fault rather than them destroying all hygiene systems, eradicated all historical records, forced Europeans to rediscover the world and once discredited went back up taking the form of Communists, Zionists, Globalists and anti-free will advocates masquerading as "Moral Guardians" and "pro-LGBT".
Note that during the medieval era Europe under the rule of the Vatican is the only place with issues with out of control Bubonic Plagues while it did not exist in any other big City in the world -- China has big cities and organic dynasties for literal millennia and the only way the rat plagues get imported there is when the Mongols got Bubonic Plague by literally invading Europe. This is not a coincidence regardless of who tells you, the establishment LOVE to keep this part a mystery.
