I'll just deal with a few things here...
My sister and brother-in-law are separating for a few months. She had to make him leave so that she wouldn't have to worry about what he's doing while she's working. He needs to make a lot of hard decisions whether the alcohol is going to control him or God is going to control him.
She prayed last night to accept Jesus as her Lord and Savior. She realized that she needed a Savior, and that she was not a good person, but a sinner in need of salvation. She's gone to church, but she's never really understood what it meant to be truly sold out to God. Now that she does, the road ahead is going to be a difficult one, but it's one that she'll have to take.
So, if you guys need to pray for anything, it's restoration in the marriage, and a need for my brother-in-law to deal with his problem, not just of alcohol, but of salvation. He needs to come to terms with the same thing, which is that we all need Christ.
