King David

So God picks the runt of the litter, and the prophet Samuel might've thought, "well, God does do things differently, so I'll anoint him and let God take care of him."
Saul is jealous of his victories.  So he keeps him close.  Jonathan and his father don't quite see eye to eye on this young upstart.  Saul fears him, then let's him marry his daughter (with a bride price of one hundred Philistine foreskins!!!), then he tries to kill him.  Did I mention the family fued between father and son?  Jonathan helps David escape.
Then there's the episode with Abigail:

David and his men camped near Nabal (one translation describes him simply by saying he "was harsh and behaved badly.") so David sent his men to greet him on a feast day and said, "look, we've been good neighbors, would you share some of your bounty?"  (Not out of character for that time!)  But Nabal rebuffs his request.  Then his servants go to his wife and say, "do you know that your husband is treating these men poorly, but they're good to have around."
David and company were on their way to attack; David said, "so much for being the nice guy.  I'll kill 'em all!"
But Abigail came and brought a peace offering, and said, "Don't mind him, he's a fool just like his name [his name is literally translated "fool"].  Here, let's not fight today."  And David relented.
Although she didn't tell her husband during the party he was throwing, the next morning, when he was sober, Abigail told Nabal all that had gone on, and he fainted dead away.  Ten days later, he died.
So David also married Abigail.  The last verses of chapter 25 of I Samuel records this, matter-of-factly:

And Abigail hurried and rose and mounted a donkey, and her five young women attended her.  She followed the messengers of David and became his wife.  David also took Ahinoam of Jezreel, and both of them became his wives.  Saul had given Michal his daughter, David's wife, to Palti the son of Laish, who was of Gallim.

 (There's a line in a song by Rich Mullins, I quoted once to a friend, "well it's right there in the Bible, so it must not be a sin, but it sure does seem like an awful dirty trick."  I was not serious then, nor was Rich, and it refers to another story, worth writing, too, but there you go -- it's right there in the Bible.)

Then it takes a soap opera to make David king after Saul dies.

The story goes on an on, but what, you may ask, is the point?  The point is that when God wrote the story, He had to work with what He had.  And all He had -- or has -- to work with is flawed, faulty human beings.  Such is the stuff of this life.  More, God is no more surprised by the short-comings of us humans today than He was back then. When I have to deal with whackos -- all too often, I think -- it's good to know that God does understand; He's had to deal with the same insanity, the same craziness, the same disorders as I do.  "Disorders" -- from the prefix "dis," which means separated from (dis-connected, dis-jointed, dis-eased); separated from order.  That is a great definition.
