A SAD TRUTH:
Christianity has indoctrinated people with the idea that all that "Old Testament" stuff was just for the Jews, and that people are now "under grace."
Nobody stops to think that "grace" has ALWAYS been around.
Grace is the reason Adam and Eve were allowed to remain alive after disobeying YHWH! (And they weren't Jews! There were no Jews until Jacob's son Yehudah/Judah started the Tribe of Judah, where the term "Jew" originated.)
Why were they kicked out? For DISOBEDIENCE to one of His commands!
What makes people today believe they have a right to perpetrate sin like Adam and Eve, and to not only get away with it, but expect to be considered holy enough to enter the Kingdom to Come?
If they ignore YHWH's Torah (Divine Instructions), they don't even know what constitutes holiness!
When you accept the God of Abraham, Isaac and Jacob, you automatically become a "Hebrew" (meaning "to cross over" like Avram/Abraham did in Genesis 12) and become a part of "Israel"....
As such, you are OBLIGATED to walk in Torah, just as Yeshua did.
1 John 2: 5 But whoever keeps His word, truly the love of God is perfected in him. By this we know that we are in him. 6 He who says he abides in him ought himself also to walk just as he walked. "(CJB)
How did Yeshua walk? By Torah! He didn't make up new rules. He kept Torah and expected US to follow suit. You can only know the him through the law and the testimony! Revelation reveals this:
Revelation 12: 17 "The dragon was infuriated over the woman and went off to fight the rest of her children, those who obey God's commands AND bear witness to Yeshua." (CJB)
Revelation 14: 12 "This is when perseverance is needed on the part of God's people, those who observe his commands AND exercise Yeshua's faithfulness." (CJB)
Please note, the above scriptures don't mention the "Ten Commandments". They simply refer to "the Commands" or "the Commandments", depending on which Bible version you use....God warns us in Proverbs 4:2 - "I give you good instruction: Do not forsake my Torah."
Torah obedience is NOT a suggestion; it is commanded! (See Exodus 12:49, Numbers 15:13-16, Isaiah 56:6, Galatians 3:28 and Romans 10:12-13.)
Unfortunately, many are blinded to that fact.
