Hi LaShae,
There's a passage tailor-made for this situation:
Likewise, wives, be subject to your own husbands, so that even if some do not obey the word, they may be won without a word by the conduct of their wives, when they see your respectful and pure conduct. Do not let your adorning be external-the braiding of hair and the putting on of gold jewelry, or the clothing you wear - but let your adorning be the hidden person of the heart with the imperishable beauty of a gentle and quiet spirit, which in God's sight is very precious. For this is how the holy women who hoped in God used to adorn themselves, by submitting to their own husbands, as Sarah obeyed Abraham, calling him lord. And you are her children, if you do good and do not fear anything that is frightening. -1Pet 3:1-6
There's a lot there to think about, concerning perfecting the character - humility, modesty, patience, gentleness, and all the fruit of the Spirit. A big tip: men love respect; they eat it up. You can work on these things, and see some results almost right away, while others will take longer to bring to fruition. But if you keep at it, you are going to change, and your husband is going to notice.
While you're doing that, there may be slightly more direct things your can do. Maybe you can discuss with him something you learned in church, or something that happened there - not just to tell him about it or make him jealous, but perhaps to get his opinion or insight. This will draw him into Body life without him having stepped in the church door! Or just talk about something the Lord showed you that helped you. These kinds of things may pique his interest and get him thinking.
Another possibility is to invite him to a home group or cell group dinner. Make sure it won't be a pressured affair, because one misguided person can leave him with a bad taste. It should be just a bunch of sincere people being real friends to each other and giving the Lord the place of honor. The friendly relational intimacy of a home group, without undue concern about doctrine or hierarchy or ritual, is the purest form of Christianity. It shows the church at its best, and may very well be the thing that convinces your husband that there is something there that he needs to investigate further.
Blessings,
