Pray for the opportunity to share the gospel with a non-Christian mother

One of our church members Sister A. decided to stay home from church to attend online services at home while her non-Christian mother visited her to stay over a month in NYC. 

 However, Sister A. came to church along with her children.  
She says, her mother told her you should go to church on Sunday, and she sent them off to church. 

Her mother didn't to come to church but she said that she would like to invite the pastor's wife to her house in Tokyo to hear her story.

While Sister A. and her children return Japan for a month or so this summer, the pastor's wife who is also returning Japan for a short period of time is more likely to have an opportunity to talk with Sister A's mother at her house. 

I'd appreciate it if you would pray that the Lord would open the mother's heart to believe and accept Jesus Christ.
