The problem is, if you are a believer in YHWH, the Creator, whether you are Jew or Gentile, whether you do or do not believe Y'shua is the promised Messiah, you are expected to know Him! It's part of the deal and it actually requires effort on your part!
In the Tanach (Old Testament) it's here:
Thus said יהוה, “Let not the wise boast in his wisdom, let not the mighty boast in his might, nor let the rich boast in his riches, but let him who boasts boast of this, that he understands and knows Me, that I am יהוה, doing kindness, right-ruling, and righteousness in the earth. For in these I delight,” declares יהוה. (Jeremiah 9:23-24, ISR)And in the Brit Chadasha (New Testament) it's here: Y'shua said:
Just as you have given him authority over all flesh that whomever You have given him, he will give to him life that is eternal. Now this is life that is eternal, that they might know You, that You are the Elohim of Truth, and he alone whom You have sent, the Mashiyach Y’shua. (John 17:2-3, AENT)How does one "know" anything?
You study! You spend time with the subject and learn it and practice it. Great sports players are great through their knowledge of the game and their practiced skills. People become good at their jobs by knowing all there is to know about their jobs and practicing what they know to do good work. Brain surgeons don't just take a scalpel and start digging around in the brain! To "know" requires the active part of gaining knowledge! We humans gain knowledge by actively seeking it and and study. (Knowledge does not just "come" to you! Remember how you were required to study to learn in school?)
Which brings me back to my thought: Why do people not know YHWH?
We have an entire Book about Him - it tells us who He is, what he expects of us, how we are to behave and treat each other, what we can eat, how to be "clean" (both spiritually and physically) so we can be in His presence, and how to gain eternal life with Him! Yet people choose to not read and study that Book, relying instead on what someone else has told them about YHWH.
YHWH is very clear in what He wants from us:
“Hear, O Yisra'el: יהוה our Elohim, יהוה is one!When was the last time you read His Words and held them in your heart, impressed them on your children, spoke of them when you sat in your house, and when you walked by the way, and when you lay down, and when you rose up? If you don't do these things, then how can you know YHWH?
“And you shall love יהוה your Elohim with all your heart, and with all your being, and with all your might. “And these Words which I am commanding you today shall be in your heart, and you shall impress them upon your children, and shall speak of them when you sit in your house, and when you walk by the way, and when you lie down, and when you rise up, and shall bind them as a sign on your hand, and they shall be as frontlets between your eyes. “And you shall write them on the doorposts of your house and on your gates.
“And it shall be, when יהוה your Elohim brings you into the land of which He swore to your fathers, to Aḇraham, to Yitsḥaq, and to Ya'aqoḇ, to give you great and good cities which you did not build, and houses filled with all kinds of goods, which you did not fill, and wells dug which you did not dig, vineyards and olive trees which you did not plant, and you shall eat and be satisfied – be on guard, lest you forget יהוה who brought you out of the land of Mitsrayim, from the house of bondage. “Fear יהוה your Elohim and serve Him, and swear by His Name.
“Do not go after other mighty ones, the mighty ones of the peoples who are all around you, for יהוה your Elohim is a jealous El in your midst, lest the displeasure of יהוה your Elohim burn against you, then He shall destroy you from the face of the earth. “Do not try יהוה your Elohim as you tried Him in Massah. “Diligently guard the commands of יהוה your Elohim, and His witnesses, and His laws which He has commanded you. “And you shall do what is right and good in the eyes of יהוה, that it might be well with you, and you shall go in and possess the good land of which יהוה swore to your fathers, to drive out all your enemies from before you, as יהוה has spoken.
“When your son asks you in time to come, saying, ‘What is the meaning of the witnesses, and the laws, and the right-rulings which יהוה our Elohim has commanded you?’ then you shall say to your son, ‘We were slaves of Pharaoh in Mitsrayim, and יהוה brought us out of Mitsrayim with a strong hand, and יהוה sent signs and wonders, great and grievous, upon Mitsrayim, upon Pharaoh, and upon all his household, before our eyes. ‘And He brought us out from there, to bring us in, to give us the land of which He swore to our fathers. ‘And יהוה commanded us to do all these laws, to fear יהוה our Elohim, for our good always, to keep us alive, as it is today.
‘And it is righteousness for us when we guard to do all this command before יהוה our Elohim, as He has commanded us.’ (Deuteronomy 6:4-25, ISR)
As you look around at the horrors going on in the world today. It's pretty clear we are in trouble - because FEW know YHWH.
It is because my people are foolish - they do not know me... (Jeremiah 4:22, CJB)
