A bit of advice to those who think there are "two Gods" ("God" & "Jesus"), and "two rules" ("Torah", aka "the Law", for the Jews & "Grace" for the Gentiles):
Open your Bible to the dividing page between the "Old Testament" and the "New Testament" and TEAR OUT THAT PAGE!
Then start at the beginning, Gen 1:1, and read, without stopping, to Revelation 22:21. You will find there is only ONE God and ONE Torah - one set of rules for ALL. Pay special attention to what the Messiah (Jesus) says, and you will find that the Messiah only came to show the way to the Kingdom of God. That's all. He didn't "change" anything God said. He didn't "nail" anything to the cross. He didn't "bring grace".
Some of your predisposition is that you have read poor English versions of New Testament scriptures and concluded that "Paul" says Gentiles are exempt from Torah. This is absolutely not true, so rule #1 while you read the Bible cover to cover is to set aside what you THINK Paul said, and read it all with an uncluttered mind - this time seeking first to understand Torah and the Messiah, rather than looking for justification to deny Torah. For example:
When cornered by the Pharisees, Jesus was asked "Which is the greatest commandment?" Jesus answered: "You should love Master YHWH your Elohim with all your heart and with all your soul and with all your might and with all your mind. This is the first and the greatest Commandment." Then He goes on: "And the second is like it. That ‘You should love your neighbor as yourself.’ On these two commandments hang Torah and the prophets." (Matt 22:37-40)
Most Christians see this as "Jesus gave only two commandments". But when you have read the Bible, cover-to-cover (having ripped out that dividing page), you will come to realize that Jesus TAUGHT NOTHING NEW! In His answer to the question "Which is the greatest commandment?", Jesus quoted only Torah! He did not give "new" commandments! For the first, and greatest commandment He quoted Deuteronomy 6:5, and for the second, He quoted Leviticus 19:18!
And note that Jesus did NOT say "there are only 'two' commandments", rather, He said "On these two commandments hang [all] Torah"! All commandments remain valid - some just don't apply to you! And He did not bring "Grace" to "replace" Torah, rather He came to spread the good news of the Kingdom of God! (See Luke 4:43) So what is the "good news of the Kingdom of God"? Well, it's not "all you have to do is believe"! No! It is found in John, chapter 17! Read it!
(Okay, I hear the outcry already! Some are clearly yelling: "But John 3:16 says: 'so that everyone who believes in him won't perish but will have eternal life.' - so all we have to do is believe!" ....Err, I suggest you keep reading John! Pay special attention to John 16:3 "And they will do these things because they know neither my Father nor myself." Then go read John 17:3 again! What is "eternal life"? Hint: It is NOT "just believe"!)
Then ask yourself "How do I 'know' the Father?"
