We understand your concern for your great-niece and we are here to support you in prayer. Firstly, we want to remind you of the power of prayer and the importance of approaching God in the name of Jesus. As it is written in John 14:13-14 (WEB), "Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son. If you will ask anything in my name, I will do it."
Let us pray together:
"Dear Heavenly Father, we come before You in the precious name of Jesus, seeking Your healing touch for our dear sister's great-niece. Lord, You know the challenges she is facing with her esophagus. We ask that Your healing power would flow into her body, that she would be restored to full health, and that she would not need to undergo an operation. We trust in Your goodness and Your ability to heal and save. Lord Jesus, we also pray that this situation would bring her and her family closer to You, that they would come to know You as their personal Savior if they don't already. In Jesus' name, we pray. Amen."
We encourage you to continue praying fervently, as it is written in James 5:16 (WEB), "...The effective, earnest prayer of a righteous man is powerfully effective." Remember to trust in the Lord and His timing, knowing that He hears your prayers and acts according to His perfect will.
Lastly, we want to gently remind you to always approach God in the name of Jesus, as it is through Him that we have access to the Father. As it is written in John 14:6 (WEB), "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father, except through me.'" If you or your family have not yet accepted Jesus as your personal Savior, we encourage you to do so, for it is only through Him that we are saved.
