You ask a wonderful question and I’ll give you the answer.
Do you believe that God created your 2 eye, 2 hands, your ability to dream, why pain exists, your ability to procreate, the beauty of women, the strength of men, diseases, the multiple types of trees, carnivores and herbivores etc? If so, don’t you wonder why?
Can you build a relationship with your wife by simply recalling the day of your wedding? Why do deep intellectual conversations seem so meaningful?
If you answers these two questions the way I would hope, then it is easy to see why the Jews (not for salvation purposes only, because that’s not the only aspect to life but it is one of many) study the Torah all day and know every aspect of God, Our Father in Heaven. How can one know if he sins if he doesn’t know the instruction manual? Sure we need salivation but why? What did we do wrong first? Why have a “whole” bible when I could probably do with a couple of verses? So just as a wife craves her husbands attention, so to God calls us to “live not on bread alone but on every Word of the Lord”, so that you can Know God!
Examples: “Patience”: God said Adam had to die but why did he wait 930 years to do it? Because although God said Adam had to die, He never said “when”; thus his years on earth were to rectify his sin.
“Kindness”: It’s easy to give when we have much and are healthy, but what about if you are 99 years old, you just have yourself a circumcision, it’s 30+ degrees out in an abandoned desert... how willing are you to serve others? Abraham shows us the definition of kindness.
“Selflessness”: When we do a good deed for one another we can always have the intention to gain something from it (which is normal), but what gain do you get when someone passes away? Nothing, it’s a completely selfless act. Abraham again shows us how much trouble he went through to bury his wife and how much he paid for the tomb.
“Wisdom”: Why is King Solomon the wisest man? Why does he say seek wisdom? What’s the difference between a wise man and a fool? Read Proverbs or Kohelet and tell me you didn’t come out a wiser man!
This is about 0.0000000000001% of the morality and depth of the Torah/Tanakh. Funny, there were “wisemen” who were so called Christians, who labelled this wisdom the “Old Testament”. Tell me, God said eternal many times to Israel, since when does eternal become old? If King Solomon said there is nothing new under the sun well before the “New Testament” then is he a liar? Only a wise man would be able to solve the mysteries and secrets of the Torah written by God. For the Torah and the Bible is not written like the books of men and sadly it is treated as such.
I truly hope this was insightful and I would be glad to share much more insight to any part of any text! “Not one jot or letter shall pass away, UNTIL heaven and earth pass”
