Well, I think each believer has their own way of recognizing such based on their own fundamental understanding of the text they believe.
This is the same with all religions not just judeo christian world views.
Depending on the depth at which you know the text, which many who ask these type of question have a cursory understanding of them, Ill try to answer
it as simply as I can.
The Old Testament is a story of Jewish history, taken from the Torah (which the Jewish books have far more than just whats in the OT that the Jewish
faith considers canonical) Also you have to start at Mosses and the Exile for the "Starting point" for basis, EVERYTHING before that point is Moses
retelling things that god supposedly told him.
So there is that for arguments sake, starting from that point and going on from there you can pretty much see an Attitude in the OT of God as being
"DO these things and you will prosper" Anything outside of doing those things gets severally punished.
Things like the Egyptian worship of multiple gods, or the slaughter of all the babies that predated Gods plague on the Egyptians of the first born.
Sodoms crimes as well are not detailed to great extent, but what you do see is that is that "New" people show up, and the crowds first response is to
try rape and murder on the new people. The only reason Lot is said to be saved is he was the only good one left in the town.
Many times you see people in the OT spared or cursed for the actions of others, things like the king screws up and the whole nation suffers, which
take alot more knowledge of the text than a cursory one to explain.
Many times a "Christians" View of the duality of the OT and NEW, comes down to OT being Gods view of SIN, and the NEW being his view of the Sinner.
The thing the bible is clear on is God did not change, hes still views those sins or crimes accordingly, just that Gods Mercy outshines his Wrath.
But again, concepts that would require much more knowledge of the text to substantiate and back up.
