just my 2 pennies here;
it could be that she is intimidated by the numerous changes you are making... i took my live in by storm, to take myself off the alcohol, then i started studying the Bible and going to church, & then eventually i demanded changes in our relationship also.. that was too much for him.. i am proud to say i made the decision for us to be together no longer--not because he disliked my changes, but because he literally went nuts. he tried to hire people to deprogram me. no joke. now, i laugh about it. but then, i was so angry at him...
anyway, pentecostal, to most baptists, is a very intimidating way to celebrate God. and many pentecostals are in it for the emotion. baptists are taught that commiting to God is yes, the emotion, w/Jesus coming into your heart, but that is it. while pentecostals see that losing control of their bodies is a sign of the Holy Spirit in them, baptists are taught that losing control of their bodies is a sign of an evil spirit in them.
also, it is important to pentecostals--the speaking in tongues, the restricted dress, the healing during services... baptists are taught that "speaking in tongues" is different languages; many women are intimidated at the restriction of no make up, no cutting of hair, no pants, & no jewelry. & many people are turned off by the fake healings publicized so much in the media, and by ministers wishing to increase their followers' faiths.
so right now?? your wife may not be seeing you as being spiritual, as much as religious.. and she may not be seeing you be as much...repenting, but be thinking that you are being fanatical. DO NOT GET ME WRONG. I AM NOT SAYING THAT YOU ARE IN THIS FOR THE WRONG REASONS, AND THAT YOU ARE NOT BEING SPIRITUAL, NOR AM I SAYING THAT YOU ARE NOT BEING CLOSE TO GOD. look at is from her point of view: she is seeing you get sober, & she sees you as "getting religion"--which many people do in their desperation against grabbing their drink. from the comments you have stated she says, it seems she thinks this is a phase.
if this is not a phase, then as the years go by, she will get more comfortable, and she will realize it, and let you lead her spiritually.
are you of the same vein many pentecostals are? that if you are following other religions, you are diminishing your chances of being a real, true, sold out Christian? if you are, then you are on a hard road. because she was not raised that way. she can't get to heaven on your coattails, and while you are the leader in the house, her relationship w/God is a highly personal and private thing.
your best bet is to pray that she grow in her relationship w/God, and that both of you see the truth in spite of yourselves as in the best way to get God to the center of your marriage.
if you feel like the pentecostal way is not the only way to get heaven, then another poster suggested you two check out other churches--and that is great advice.. there are numerous churches that are active and animated in their services w/mounds of joy and excitement, but w/out the speaking in tongues, the limited dress and jewelry wear, the public display of healing in their services....
again, just my 2 cents worth...
