I've spent some time thinking over why God tolerated Aziraphale lying to her face and all of his later numerous defiances to her will. I think I've finally got it.
Aziraphale and Crowley are God's two favorite Game Pieces.
Crowley is an obstacle and Aziraphale is a wild card.
It all comes down to the fact that the Good Omens Gods is an all-powerful, presumably omniscient entity, playing an ineffable game.
And the thing is, when you're all powerful, presumably omniscient entity, holding all the cards, any game you play will be pretty damn boring.
And that is where Aziraphale and Crowley come in.
You can't just create a universe, run it for a few thousand years, and then stop.
Crowley does a lot of things. But his main role in God's game is to serve as an obstacle, an obstruction to the plans of both Heaven and Hell; her plans. From the beginning of the show, even when he's messing up the basic delivery of Antichrist, he's essentially performing this function. However, Crowley's obstruction is not random, he becomes an obstacle for specific and predictable reasons, as we've seen throughout the show. What's unpredictable is the outcomes that result from his interference in God's plans. He often takes upon himself to defy God.
Age does not wither, nor custom stale his infinite variety.
Translation from the words that inspired Shakespeare: He's unpredictable! (another reason he is forever compelling to Crowley)
Ever since Aziraphale "Prometheus"-ed away his flaming sword to Adam and Eve, God was probably satisfied to label him as a wild card and left him alone to do his thing. Narratively, he's served that function. He's tied and pulled in many directions, to the point where it was uncertain where he would fall in season 1. He lied to both Micheal then Crowley over where Adam was, he possessed a human like a demon, and yet his decision allowed both him and Crowley to be there in Tadfield to influence Adam when the time came. That's not touching on his mad choices/interferences in season 2. He often takes upon himself to correct God depending on how he interprets Heaven's commands.
Together, Aziraphale and Crowley make the game much more entertaining for God. Hell, she might even ship it. I'm positive the God's real game in the Job episode actually revolved around Aziraphale's and Crowley's actions, not her bet with Satan (if that even happened).
(The real question is if God has started a new game or is continuing her old one.
