I suspect there will be many responses to Kristy's call for prayer.  All of them should tell her to take a step back and look at the situation she is in and get out of it as fast as she can.  She is unequally yoked and all the talking and preaching in the world is not going to change the hearts of her fiance or his mother.  Kristy, do not take being unequally yoked lightly.  2 Corinthinans 6:14 (NIV):  "Do not be yoked together with unbelievers.  For what do righteousness and wickedness have in common?  Or what fellowship can light have with darkness?...What does a believer have in common with an unbeliever?...For we are the temple of the living God....Therefore come out from them and be separate, says the Lord."  The footnote in my Bible says:  "In God's eyes people ultimately are divided into two categories:  those who are in Christ and those who are not.  Therefore, believers must not be in voluntary partnership or in intimate association with unbelievers, for such relationships can corrupt their relationship with Christ.  This includes partnership in business, secret orders (lodges), dating, marriage and close friendships.  A Christian's association with unbelievers should be only such as is necessary for social or economic existence, or to show unbelievers the way of salvation."  You have delivered the message; they have refused to accept it.  You are not expected to obligate yourself and your children to a lifetime of misery for the sake of this man and his mother.  Jesus paid the price, not you.
 
You can continue to pray for the blinders to be removed from their eyes, but not as a part of their family.  You may not be aware that your emotional attachment to this man may have caused you to put him on a pedestal, subjecting yourself to the sin of idolatry.  Many of us unwittingly do that with another human being.  If the "cult" you are accused of being involved with is centered around Jesus Christ, His death, resurrection, and soon return, then I guess most of us are members.  You may not know a lot about the Bible, but your heart seems to be in the right place.  If you are not involved with a Spirit-filled church, start looking around.  Also, if you have not already done so, seek the baptism in the Holy Spirit and you will be amazed at how much will be revealed to you.  But for right now, you really need to get out of the shackles of the relationship with this man and his family.  If you wish to continue your pursuit of Christ, He needs to be #1 in your life.  If this man is to be your husband in the future, you will have to let the Lord do His work in him BEFORE you tie yourself down to a life of misery.  Step back, step out, let the Holy Spirit mature you a little more, lean on Him for the right mate.  It won't be the easiest decision for you to make, but it will be the best.  By the way, praise and worship works wonders in healing the wounds!
