It is very encouraging to see that you have been loving and caring to your mom.  With her inappropriate words and behavior, I realize this can be a difficult task.  By your question, I assume your mom still lives at her home, but now wants to live with you because of her finances.  Your husband can no longer tolerate your mom and you are afraid that her presence in your home will cause problems in your home.  I hope I have understood your problem properly.

1 Timothy 5:4 says to us, “But if any widow have children or nephews, let them learn first to shew piety at home, and to requite their parents: for that is good and acceptable before God.”  For the believer, we understand that the Lord has given us responsibility towards our aging and ailing parents.  Since you only mentioned your mother, I will assume that she is a widow.  When we think of how our parents sacrificed so much during the course of our lives, we normally will do all we can to help them.  It seems you are doing that already.  This honors the Lord!  I’m sure your mom appreciates all you and your husband are doing for her, even if she doesn’t express it.  Her inappropriateness could very well be an indication of a degree of dementia, and she may be helpless to change her behavior.

1 Timothy 5:8 goes on to say, “But if any provide not for his own, and specially for those of his own house, he hath denied the faith, and is worse than an infidel.”  That would include infirmed parents who need our help and/or support.

I do understand your concern that by moving your mom into your home, it may destroy the peace there because of your husband’s feelings towards her.   Have you and your husband prayed about this together?  I suggest you do pray about it and ask the Lord to give you both the resolve to care for your dear mom in spite of her improper behavior.  It is so important that you two are of one mind about this so that you may continue to work together for your mother’s care.

I do want to offer a different scenario for you two to consider.  You pointed out that your mom’s main concern was being able to afford to pay her electric bill while living alone.  Could you afford to help your mom with her bills so that she can continue to live independently?  This would relieve your concern of having her in your home and not having peace in your home…which is very important for the health of your marriage.  Do you have any siblings that could contribute money so that she might stay in her own home?  She may even qualify for some government assistance if she is considered low income.  These are options you can look into, pray about, and make a decision that is agreeable with all involved. 

I appreciate you for your desire to help your mom.  It is proper and scriptural that you honor her with your love and assistance, if needed.  We read in Ephesians 6:2, “Honour thy father and mother; (which is the first commandment with promise.)”  It may be a difficult task to help your mom and please your husband at the same time.  However, if you and your husband can give this situation over to the Lord, I’m sure He will lead you to an answer that will help keep the peace in your home and also provide for your mother’s needs. 

I will leave you with this verse to consider.  1 Peter 5:7 says, “Casting all your care upon him; for HE (CHRIST) CARETH FOR YOU.”  (CC)  (544.2)
