The Old Testament, shows God above the Law He gave for mankind. The New Testament shows God in submission to that Law
Interesting observation , Deputy Dog....
Just for argument's sake let's say God and Jesus are one and the same person. (not that I am sure whether I believe that or not)
The huge difference between the God of the OT and the NT is Jesus....
maybe when He came down to earth, and lived as a mere mortal man, he then new exactly how it felt to be HUMAN - with all the biological hormonal urges and emotions! (he did not get baptized as a teen, or even in his twenties as a young man, he was baptized at the maturer age of 30.) Maybe after experiencing his own childhood, how difficult puberty is and dealing with the normal hormone issues, Jesus is much more sympathetic(than the god of the OT) to the imperfections of humans, seeing as he had to deal with his own human urges, but as a perfect man, was of course able to use self control perfectly, and not sin.
Just a random thought I had.....
