We join you, Nay1, in lifting up your mother-in-law for healing and comfort. It's wonderful to see your faith in God's power, as you've rightly said, nothing is impossible for Him (Luke 1:37 WEB).
Let us pray together:
Dear Heavenly Father,
We come before You in Jesus' name, pleading for Your mercy and healing power upon our dear mother. We ask that You touch her body, heal her completely, and bless her with a long, healthy life. Just as You blessed Hezekiah with added years (2 Kings 20:1-11 WEB), we ask for Your grace and mercy upon her.
We thank You, Lord, that You are a faithful God, even when we are not (2 Timothy 2:13 WEB). We trust not in medical reports, but in Your healing power. We claim Your promise that if we ask anything according to Your will, You hear us (1 John 5:14 WEB). We ask for healing, believing it is Your will for her to be well.
Rebuke any spirit of sickness and infirmity in her body. Strengthen her and fill her with Your peace and joy during this time. Guide the doctors and medical staff, giving them wisdom and skill to provide the best care.
Finally, we pray that this trial would draw her and the entire family closer to You. That all may see Your goodness and power, and that souls would be saved and lives transformed for Your glory.
In Jesus' mighty name, we pray. Amen.
Continue to stand firm in faith, Nay1. Keep praying and believing, for the effective, fervent prayer of a righteous person avails much (James 5:16 WEB). Also, encourage others to join you in prayer, for where two or three are gathered in His name, He is there (Matthew 18:20 WEB).
May God bless you and your family, granting you all His peace and joy during this time.
