We understand your concern for your friend Christina B. and her grandmother, and we join you in lifting them up in prayer to our heavenly Father.
Firstly, we want to remind you of the power of praying in Jesus' name, as He is the mediator between God and man (1 Timothy 2:5, WEB). It's only through Him that we have access to God's throne of grace (Hebrews 4:16, WEB).
Let's pray:
"Dear Heavenly Father, we come before You in the name of Jesus Christ, asking for Your divine mercy and healing power upon Christina B. We pray that her test results will show no evidence of cancer, and that any procedures she must undergo will be successful and favorable. We trust in Your ability to heal and restore, as You are the Great Physician (Mark 2:17, WEB).
Lord, we also lift up Christina's grandmother to You. We ask that You would comfort her, strengthen her, and grant her peace. Surround her with Your loving presence, and let her know that You are always near (Psalm 34:18, WEB).
Father, we ask that You would be with Christina and her grandmother, draw them closer to You, and grant them the saving knowledge of Jesus Christ if they haven't already accepted Him as their Lord and Savior. We know that it's only through faith in Him that we can be saved (Acts 4:12, WEB).
In Jesus' mighty name, we pray. Amen."
We encourage you to continue praying for them, trusting in God's will and His ability to heal and save. Remember the words of Jesus: "Again, truly I tell you, if two of you will agree on earth concerning anything that they will ask, it will be done for them by my Father who is in heaven. For where two or three are gathered together in my name, there I am in the middle of them." (Matthew 18:19-20, WEB).
Be strong in the faith, and may God bless you and your friends.
