I use to be a member of a church of christ. But, by God's grace, some kids I met invited me to their bible study and they watched lectures by Sproul at their bible study. I began to take an interest in theology and before too long...I could no longer accept the things being taught at the CoC and I left. It's not easy, I wrestled with it for a long time, and they even had someone try to convince into coming back, but by that time I had already come to accept DoG and there was no convincing me to come back there. My advice would be just to be patient with her. I can almost guarentee she is struggling with the issue on the inside. Just keep using lots of scripture too.
I'll keep her in my prayers.

"And have we now forgotten that powerful Friend? Or do we imagine we no longer need His assistance? I have lived a long time; and the longer I live, the more convincing proofs I see of this truth: that God governs in the affairs of men. And if a sparrow cannot fall to the ground without His notice, is it probable that an empire can rise without His aid? We have been assured, Sir, in the Sacred Writings, that 'except the Lord build the House, they labor in vain that build it.' I firmly believe this; and I also believe that, without His concurring aid, we shall succeed in this political building no better than the builders of Babel." -Benjamin Franklin
