Sparky,
I just got home and saw this thread.....
Brother, you know I care for you and love you with the love of Christ. So, please remember that as you read this.
This is a messy situation, to say the least. I do not think you should cut and run, if that means never seeing Her again. However you are living in a Sinful relationship with someone who is not your wife. I know that God does not honor sin, hers or yours. So, what are you to do?
First, her drinking and lying is an issue. Learning to openly communicate with each other is important if a relationship is to succeed. Forgiveness is available for the lying and even the drinking. If you have told her you will stick with her, though this, then do, however, help her seek professional help. Help her find counseling. Do you two attend Church together? Has she accepted Christ as Her Saviour? Do you two discuss these things?
You have been living with her for some time now, in a relationship that I am sure is intimate. Why have you not married? Living together outside of marriage is one issue here. Marry Her now or move out. This does not mean that you should kill the relationship, but in means stop living as Husband and wife if you are not husband and wife. What I mean is stop having sex and doing the things that only man and wife are to do. God never honors a relationship that is built on sin.
Once the relationship is approved of God, then He will honor it. The way for it to be approved is for it to be righteous in His eyes.
1. Both of you must be His Children. You both must confess Christ as Lord of your life.
2. You both must live according to His will for you as individuals, allowing Him to sharpen you, and correct you. (Guide against person sin)
3. Avoid, relational sins, (namely fornication and Idolatry) if she is ahead of God in your life than she has become an idol for you. If you are having intimate relations that is fornication and the Bible calls it sin.
Sparky, You must confront the drinking problem. It will not go away! She will never be over it! She can be helped, but I fear that the drinking is also compounding the spiritual issues between you two. Please seek some local counseling through the Church. Also, consider how you or she could move out until the wedding, and clearly understanding that the wedding should be put off until the drinking issue is well into a treatment program. Each time a Christian couple comes to me and ask me to perform their wedding service, I ask them for there testimony and about the depth of the physical relationship. If they are sexually active, I tell them I cannot perform the wedding unless they can repent of this sin, and abstain until the Honeymoon. If they agree, then we pray a prayer of repentance right then. Brother, I am praying for you both. Consider this and let us know what happened.
God Bless you
Your Pastor T
