Throughout the Old Testament psalms and texts say God is slow to anger and that God is merciful.
There are texts where God was going to bring retribution down on His people . A prophet is sent to tell them to repent, and to recount prophesies given by God.
Jonah, as a prophet, a reluctant one, first runs from God, ends up in a storm in a boat, gets thrown overboard so as to save the boat and it’s sailors,
gets put into the belly of a big fish, then decides to do as God wills.
Jonah goes to the town God wants to hear his words, of retribution. Those in the town immediately fast, do penance and wear sack cloth in the hope God won’t bring down this retribution.
Now Jonah goes outside the city, sits and watches and waits for the event he has warned will happen.
It’s hot, God grows a castor oil plant for him for shade. Next day God sends a worm to eat the plant and makes it very hot for Jonah, who is still sitting and waiting and seems disappointed with God the town still stands.
In the Old Testament we read of the real relationship God has with His people. And of times prayer and request has been granted because of the intercession of holy people or indeed all the people.
In the New Testament Jesus says the only sign this generation will get is that of Jonah, when they ask for signs.
Surely many of the Old Testament people would be Saints
