I agree totally.
But then Jesus appeared and so did the religion that came to be known as Christianity.
Christianity believes in the 10 Commandments, but they are not a tenet of the Christian religion....
they signify Christian morals that must be kept.
The 10 Commandments are believed by all religions.
This does not make the participants of that religion Christian.
Excellent...yes sir, Jesus was present in the OT because He always existed.
Perfect.
I like to say that the first 3 commandments are about God and how He is to be worshipped.
The 4th is to honor our parents.
And the rest are the do nots....the Moral Law.
Yes sir.
No one has seen God except He that was with Him...
John 1:18
18 No one has seen God at any time; the only begotten God who is in the bosom of the Father, He has explained Him.
I believe we need a formula because many would not be able to come to the conclusion you have been able to see.
Unfortunately, not all are as astute as you are and most of us need explanations. Personally, for me, I don't know if I would ever have been able to see the Trinity in the OT and the NT unless it had been shown to me at some point.
Thanks for a very good, complete and spirit-filled post !
