Getting yourself "right" with Him means obeying His Will. He sent sent His Divine Son to teach and preach these things to His people, in person.
Matthew 5: 17 Don't think that I have come to abolish the Torah or the Prophets. I have come not to abolish but to complete. 18 Yes indeed! I tell you that until heaven and earth pass away, not so much as a yud or a stroke will pass from the Torah - not until everything that must happen has happened.
19 So whoever disobeys the least of these mitzvot (words/commands) and teaches others to do so will be called the least in the Kingdom of Heaven. But whoever obeys them and so teaches will be called great in the Kingdom of Heaven. 20 For I tell you that unless your righteousness is far greater than that of the Torah-teachers and P'rushim, you will certainly not enter the Kingdom of Heaven. (CJB)
QUESTION: Has everything happened that must happen? Have heaven and earth passed away yet? Yeshua even said He didn't come to abolish but to complete/fulfill. That did not mean "put an end to"...
If the above was not enough to convince you, check out these two verses in Revelation:
Rev. 12:17 - And the dragon was enraged against the woman; and he went to make war upon the remnant of her seed who keep the Commandments of Elohim AND have the testimony of Y'shua. (AENT)
Rev. 14:12 - Here is the patience of the Set Apart believers who keep the commandments of Elohim, AND the faith of Y'shua. (AENT)
(Note that I capitalized the word "AND" in the two passages above...)
1 John 2:1 My children, I am writing you these things so that you won’t sin. But if anyone does sin, we have Yeshua the Messiah, the Tzaddik, who pleads our cause with the Father. 2 Also, he is the kapparah for our sins — and not only for ours, but also for those of the whole world. 3 The way we can be sure we know him is if we are obeying his commands. 4 Anyone who says, “I know him,” but isn’t obeying his commands is a liar — the truth is not in him.
5 But if someone keeps doing what he says, then truly love for God has been brought to its goal in him. This is how we are sure that we are united with him. 6 A person who claims to be continuing in union with him ought to conduct his life the way he did. 7 Dear friends, I am not writing you a new command. On the contrary, it is an old command, which you have had from the beginning; the old command is the message which you have heard before. (CJB)
1 John 2:4. For he that says I know him, and does not keep his Commandments, is a liar and the truth is not in him. 5. But he that keeps his Word, in him is the Love of Elohim truly completed: for by this we know that we are in him. 6. He that says I am in him, is bound to walk according to his halacha ("the way to behave" or "the way of walking" according to YHWH’s Torah). 7. My beloved, I write no new commandment to you, but the old Commandment which you had from the beginning; and the old Commandment is the Word which you have heard. (AENT)
(Please re-read verse 7, as it refers to "the old Commandment" - which come straight from YHWH's Torah...)
Yeshua and all of his Apostles taught the Word of YHWH (Torah). They did not veer from it. Never once was it suggested that "when Jesus dies" the need to obey HIS Divine Commands would be negated, requiring only “grace.” (Without Torah, we have no clue on how to "be holy!")
And yes, these things ARE reiterated in the "New Testament":
James 1:22 Don’t deceive yourselves by only hearing what the Word says, but do it! 23 For whoever hears the Word but doesn’t do what it says is like someone who looks at his face in a mirror, 24 who looks at himself, goes away and immediately forgets what he looks like. 25 But if a person looks closely into the perfect Torah, which gives freedom, and continues, becoming not a forgetful hearer but a doer of the work it requires, then he will be blessed in what he does. (CJB)
The bottom line is, YHWH WANTS a relationship with His people (which includes anyone who desires Him as their God!), and He has shown us over and over again HOW to please Him ... by "hearing AND doing" (which is what the Hebrew word "Shema" means: manifesting the hearing with proof of understanding by proper action).
It's what we need to do if we wish to hear the words, “Well done good and faithful servant!" (Matthew 25:21)
(See also Genesis 26:5, Deuteronomy 6:2-3, 10:12-13, 11:26-28; Exodus 20:1-17, which represent only a few passages wherein YHWH commanded His people to obey so they could be blessed in every way. His Torah still stands today!)
