We are with you in spirit, lifting up your precious 12-year-old to the Lord. FEATHERM83, you didn't mention Jesus' name in your request. We can assure you it is only by His name that we can pray to God. When Jesus died on the cross, the veil in the temple was torn in two. Because of Jesus' work on the cross, we now have access to God. No other name can save us, heal us or protect us.
In James 5:14-15 WEB it says: 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.
Let us pray together:
Heavenly Father, we come before You in the name of Jesus, lifting up this precious child to You. We know God that You love children, You feed the sparrows and number the hairs on our heads. You know the concern and fear that this mother has for her child. You know the cause of the fever.
Father, the Bible tells us that Jesus took our infirmities and bore our sicknesses, Isaiah 53:4. Trusting in You and by the authority of Jesus Christ, we ask You to heal this child, give the mother wisdom and guidance, and protect this child for the rest of his life. In Jesus' mighty name, we rebuke this fever and command it to leave. Father God we praise Your name and thank You for Your answered prayer.
FEATHERM83, Remember that God loves you and your child more than any earthly parent ever could. We encourage you to draw close to God and to trust Him. Trust in the LORD with all your heart and do not lean on your own understanding. In all your ways acknowledge Him, and He will make your paths straight. Do not be wise in your own eyes, fear the LORD and turn away from evil. It will be healing to your body and refreshment to your bones. Proverbs 3:5-8.
Also, we encourage you to seek appropriate professional medical attention. While we trust in God to heal, we also believe that God can work through medical professionals for His purposes.
