I tried once to Strong Arm my mother into the body of Christ, and all that did was cause great division, now I just love and pray for her, and let Christ take over and slowly I see some change in her........
Not sure what you mean by "strong arming" your mother but all we can do is present the Good News, to the extent that people are willing to listen and let the Holy Spirit take over. If your mom rejects it, she isn't rejecting you and your news.
That you "see some change in her" is heartening and you are praying for her is great.
