Oh, my gosh, the dancing on the side of the highway. A little bit before Before Adam Mitchel's daughter dies, she asks her dad to dance with her on the side of the road when her favorite song plays on the radio while they are driving. Adam declines because, well, it's kind of embarrassing. So, instead she teaches him how to dance for next time by acting like she is holding him as she dances. It's adorable, but the real heartwarmer is when a little after after she dies, Adam goes to the same spot on the side of the road and plays his daughter's favorite song and walks outside. He than starts dancing as a voice over of her teaching him to dance plays while he dances. Note that this was one of those dances that involve holding the other person. This troper needed a few tissues after that. Even more heartwarming in the novel version where after he does the dance, we see Emily in heaven with Jesus who tells her that one day she will see her family again in the eternal kingdom and dance with her father again; then he scoops her up "like she was his most precious creation" and she happily snuggles into his chest.
Also heartwarming is the dinner scene after the "Snake Kings" scene. The Mitchels are laughing happily when Adam says that he had a good day. In the quiet of his wife and son sobering, he states that they're going to be okay. Then his son says out of the blue "I wish I had been a better brother..." The three family members end up in a crying group hug as Adam reaffirms his love and care for his son and reassuring him that he's not to blame for anything involving his sister.
When the cops and Javier are sitting around discussing being godly fathers, Adam asks when the other men felt they had become men. Most of them give halfhearted unsure answers but Javier says, with a warm smile and utmost conviction, "When my father told me I was." In the novel, there's an added subplot with Javier's father and what a good man and good father he was, with Javier regularly claiming if he can be even half the father his own was to his children, they will be truly blessed.
When Javier tries on the suit he's going to wear for signing the Resolution, his children come in and marvel over how amazing he looks. He regards his reflection and remarks "I feel like a rich man."; his wife then informs him that he is a rich man because his God loves him, his wife adores him and his children honor him.
You may need a few tissues after some of these, which cross into Tear Jerker moments:
After Emily's death, Adam and Victoria are in her room talking. The camera pans up to a shot of a placard above Emily's bed that reads, My prince did come, his name is Daddy.
Near the end of the film, Nathan takes his daughter Jade to dinner at a fancy place the family would normally not eat at since they can't normally afford it. In a ceremonious moment, Nathan asks Jade to trust him with her heart until God shows them both who she should marry. He then gives her a heart-shaped promise ring.
A deleted scene makes this even more so on both levels. A woman Nathan's age comes over after he steps away briefly and informs Jade that she'd have given anything to have her father be that involved in her future when she was Jade's age and informs her "You have a wonderful father.
During the climactic shootout, the gang targets a little girl, intending to use her as leverage against the cops. She runs for her house screaming for her daddy, who grabs her and actually tries to wrestle her attackers. Once it's all over, Adam is concerned about her and reassured she is all right. We see the girl in her father's arms.
