I agree that this is a great test for you and your faith in Christ. I think that Christ has to come first before any church. Remember also that the effectual fervent prayer of a righteous man avails much. You have a prayer challenge - to pray for your wife and not give up no matter how long it takes. I have prayed for my wife every day for the last 26 years that the penny will drop and she will have a fresh revelation of Christ in her life. My challenge is always to present the best example of a Christian believer in front of her, not only spiritually, but in all the different activities of life both at home, work, and church. When we moved from Dunedin NZ (where my wife grew up) to a city where she had never been to, I did not go to church for the six years we were there because I was not prepared to go swanning off to church meetings leaving her alone at home, especially in the evenings. It was only when we got to Auckland and the church was 5 minutes walk from home that I decided to go back to church.
My wife is not theological, so my flights of fancy in theology does not impress her much, nor my Pentecostal beliefs. We went to a local AOG where our 16 year old daughter was attending at the time, for her baptism and everyone in the service was speaking in tongues. My wife had eyes like saucers and asked me, "Are those people speaking in tongues?" I said, "Yep." She said, "It's not my cup of tea!" And that was it. It was funny really, because when I went to give an Abrahamic blessing on my daughter as she came out of the waters, it came out as a tongues message, and my wife had never heard me speak in tongues before! I then gave the interpretation. When we got home, she never said a word about it. I think that she just accepts me as I am with all my strange bits (as she sees them). But what has kept us together for so many years is our mutual respect for each other and the willingness to allow each other to have our own space.
But she will correct me when I do something that is "not Christian". I was rude to a salesperson once, and she told me off to a treat! I had to go and apologise to the salesperson afterward. If she uses unsavioury words at a villain in a soap opera she is watching, I will say, "St Pius won't like that!" She then asks, "Are you making fun of my religion?" I say, "Yep." And then we have a laugh about it.
Yet for all that, she shows an interest in what goes on at church, she counts many as her friends as well as mine, and she reads the church bulletin when I prepared it, also when I come home from a Managers or Elders meeting she asks me how the meeting went.
What I think would help is that you not require your wife to attend the worship services if she doesn't want to. But include her in the social side. But with that, don't allow anyone to button hole her and lecture her about what she should be doing in the church. You may have to be assertive in your defence of your wife. She will appreciate that, even if she doesn't say anything. If people won't stop when you tell them to, then complain in writing to the pastor, and if he doesn't do anything, write to the General Superintendent (if your church has one). You need to show your wife that you will be fiercely loyal and protective of her no matter what. If you have ever watch the Hanna Barbera cartoon about Yakki the Duck, the fox and the bulldog, you will know what I mean. Your wife is Yakki and you are the bulldog, while others who button hole your wife are the fox. You can then say to your wife, "You'd better close your itty bitty little eyes because you shouldn't oughta watch this!" And then you can be the fierce bulldog to the insensitive, religious person who is trying to pounce on your wife.
Even though I might question some of the prophetic stuff, I am not denying it because that is something personal between you and God. But with every promise there is the condition. It may very well be that if you are totally supportive of your wife where she is at, and defensive of her in front of all others, then that may be God's condition for you to be promoted to greater ministry for Him. There is a sequence: The Promise, then the Problems, then the Provision. I think you have the promise, but now are working through the Problems stage. This may take years. I completed my MDiv at the age of 68 after a wonderful three year journey, with the full support of my wife. I am now learning NT Greek. She doesn't understand why I want to do that at my age, but I told her that I am doing it to keep my brain alive. She ended up giving me that old fashioned look!
If you are able to let your wife be her own person, even though that doesn't involve church, and seek to support her particular gifts and the things she loves to do, even though that might be a sacrifice for you, your marriage will take on a new dimension of happiness and fulfillment. The Scripture says "in honour preferring one another". That means that I might have to give up things that are meaningful for me, to allow my wife to do the things that are meaningful to her. Something to think about.
