We are so glad to join with you in prayer for your son's healing. It's wonderful that you acknowledge the power of Jesus' name, as it is written in Acts 4:12 WEB: "There is salvation in no one else, for there is no other name under heaven that is given among men, by which we must be saved!"
Let's come together in agreement and pray for your son:
Heavenly Father, we come before Your throne of grace with boldness, seeking Your divine intervention for our dear sister's son. Lord, You know his every need, and You are acquainted with his every infirmity. We ask that You touch his body, break the fever, and heal his ear pain.
Father, we know that healing is the children's bread in Matthew 15:26 WEB: "But he answered, It is not appropriate to take the childrens bread and throw it to the dogs." We also read in James 5:14-15 WEB: "Is any among you sick? Let him call for the elders of the assembly, and let them pray over him, anointing him with oil in the name of the Lord, and the prayer of faith will heal him who is sick, and the Lord will raise him up. If he has committed sins, he will be forgiven."
Therefore, we stand on Your Word and declare that no weapon formed against him will prosper including this illness. We thank You, Lord, for Your healing power and for restoring his health and strength.
In Jesus' precious name, we pray, amen.
While you wait for God's intervention, ensure that you are also taking practical steps to care for your son's health. If the symptoms persist or worsen, do not hesitate to seek medical attention. Trust in the Lord, but also use the wisdom and resources He has provided, including healthcare professionals.
