Yesterday, I called my son and daughter into the kitchen to come and help me. My son said "I'll be there in a minute. I just need to finish this." That was fine. My daughter, however, got all upset and wouldn't come. I called again, "Joanna, please come here now." She came into the kitchen having such a tizzy fit that I quietly told her "You have lost the privilege of using the computer for the rest of the day." See, she had been on the computer and didn't want to stop. Once she realized that she lost the computer, she had an absolute melt-down. She's 9 years old and knows better. I sent her to her room and told her when she has control of herself to come to the kitchen and we will talk.
About 5 minutes later, a sniffling, sobbing little girl came to the kitchen and said "I'm sorry Mommy. Can I get the computer back?" See, she was sorry just because of having been punished. When I told her that she was forgiven but she would not get the computer back, she went off again and was sent back to her room. She stayed there quite some time before she came down again and apologized again, we reconciled and that was it. She knew she still was not getting on the computer.
Later in the day, she came to me and said "Mommy, when I apologized and said I was sorry, I said that so that you would forgive me but I wasn't really sorry yet. But I realize that I shouldn't have reacted that way and that you were right for punishing me. I'm really sorry for making you sad and I will try to not do it again." She's getting it now. Now instead of just being sorry, she had repented - she was turning from what she had done as well as being sorry. That is a result of the Spirit in her.
Just being sorry doesn't make God choose us. Just believing that we will be forgiven makes God choose us. That is not at all Scriptural. Instead what is Scriptural is grace from God that helps us to see our sin and allows us to turn from it. An unsaved person is never going to be truly sorry for their sin - and even understand just what their sin is - until they bow at the feet of Jesus after their death.
The Biblical model is that not that we make God choose us for what we've done but instead God chooses us because of His mercy. That's it.
