People popularly think he is more forgiving than he is, in new testament (he isn't, for example he explicitly says he "brings the sword", he more than once displays he is at least annoyed with people, and the famous passages about giving the other face and so on are more about civil disobedience than forgiveness)
And people like to portray old testament God as unforgiving (he isn't either. he did forgive people a bunch of times, and was very patient, and some of episodes that understood today as cruel, were necessary for one reason or another, for example when he told Israelites to execute the children of their enemies after a particular battle, the reason for that is the battle happened in the middle of the desert in a place with not enough food for both groups, it was either execution or abandon them to starve on the desert on their own).
