Certainly, here’s a heartfelt prayer for your sister and friend during this challenging time:
Dear God,
We come to You in this moment, seeking Your comfort and strength. We lift up [Sister/Friend's Name] as she faces the heavy weight of her heart. Lord, You see the pain she carries from grieving her dad, and now the uncertainty surrounding her mom.
Please surround her with Your love and peace, reminding her that she is not alone in this journey. Grant her the courage to face the challenges ahead and the strength to support her family as they navigate these trying times.
Lord, we ask for healing for her mom and wisdom for the medical team caring for her. Fill the hearts of [Sister/Friend's Name] and her family with hope, and let Your light shine through their darkness.
May they find solace in the memories of their loved ones and the love that surrounds them. Help them to lean on each other and on you, finding comfort in the community of friends and family during this time.
In the name of Your love, we pray.
Amen.
