We are with you in spirit, lifting up your grandmother and your family during this challenging time. First, let us remind you that God is our ultimate healer and comforter. As the Bible tells us, "Don't be anxious about anything; but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus." Philippians 4:6-7 (WEB).
Let us pray together:
Dear Heavenly Father,
We come before You today, lifting up our sister and her grandmother. Lord, You are the Great Physician, and we trust in Your healing power. We pray for the doctors and nurses who will be performing the surgery, that You guide their hands and give them wisdom. We pray for strength and comfort to the family standing in the waiting room.
Lord, we know that Your will is perfect, and we trust in Your plan. We ask that You bless our sister and her family with peace, and that You heal her grandmother. We ask these things in Jesus Christ's name.
Our sister, remember that God is with you and your family during this time. Stay strong in your faith and trust in Him. As written in 2 Chronicles 20:15 "Thus says Yahweh to you, 'Don't be afraid, neither be dismayed by reason of this great multitude; for the battle is not yours, but God's."
You mentioned that your grandmother has a strong faith. That is a wonderful blessing. Encourage her with the words of Psalm 23:4 "Even though I walk through the valley of the shadow of death, I will fear no evil, for you are with me. Your rod and your staff, they comfort me."
