At times like these I am at a loss as to how to pray. So when in doubt look to your handy Bible reference via google. I found this prayer online and felt that it captured all the things I wanted to say to God. If you want to pray but find yourself in the same situation as me ... then this one may be of use.
Dear Lord,
You know my Mom so much better than I do. You know her sickness and the burden she carries. You also know her heart. Lord, I ask you to be with my Mom now, working in her life. Let your will be done in her life. If there is a sin that needs to be confessed and forgiven, Lord, please help her to see the need and confess ... though based on what I see there is none. Lord, I pray for my Mom because your Word says I should pray for her healing. I believe you hear this earnest prayer from my heart and that it is powerful because of your promise. I have faith in you to heal Mom, but I also trust in the plan you have for her life. Lord, I don't always understand your ways, and why my Mom has to suffer, but I trust you. I ask that you look with mercy and grace toward my Mom. Nourish her spirit and soul in this time of suffering and comfort her with your presence. Let Mom know you are there with her through this difficulty. Thank you for giving her to us and thank you for all the blessings you have worked through her. And may you be glorified in her life and also in mine. Amen.
