Sorry for not replying sooner (like I said, not much time on here now).
This particular son says he believes (I'm not so sure though- as bad as that sounds), will tell other people how much he loves G-d, and judges (in a bad way) other believers (i.e. "I would never do that", "I would just tell people what G-d says to do about that"); however, he is totally disrespectful when we have our Bible studies and at church. He really believes he knows everything there is to know about the Bible and G-d's commands. (He's 10 and doesn't do any Bible reading on his own so that is definitely not the case.)
We've spent months now trying the gentle, encouraging route and hoping it would get through his head, but after the bragging about how good he is lately we decided that, if he thinks he knows so much about the Bible, he needs to be able to look up the words to the verse of his choosing and figure out (with our help) how it applies to his life. I'm just hoping it doesn't make him more arrogant.
That's great that she agreed to pay for childcare! I hope it all works out!
