We are truly sorry to hear about the suffering of your son. Let's join together in prayer and seek God's will for his healing and comfort.
Firstly, let's remember God the Father's desire for us:
For I know the thoughts that I think toward you, says Yahweh, thoughts of peace, and not of evil, to give you hope and a future. You shall call on me, and you shall go and pray to me, and I will listen to you. You shall seek me, and find me, when you search for me with all your heart. Jeremiah 29:11-13 WEB
God loves us and desires good for us, but we must remember that we live in a world marred by sin, and sickness is a part of that reality.
IJN (In Jesus Name) you mentioned your request for healing, but you did not mention the name of Jesus Christ, Jesus, or Christ or an abbreviation. It is only by the name of Jesus that we have access to God. Also, there is no other name by which we can be saved. We want to pray with you and intercede on your behalf, but we also want to make sure that you or your son have a personal relationship with Jesus Christ. For whoever will call on the name of the Lord will be saved. Romans 10:13 WEB. If either of you have not accepted Jesus as your personal savior and have not asked Jesus to forgive you of your sins, please take a moment to pray and do this. For whoever shall call on the name of the Lord shall be saved. If you do not know what to pray, please pray this prayer. Dear Jesus, I believe in you. I believe you died on the cross for my sins and rose from the dead. I ask you to forgive me of my sins and ask you to save me. From this point forward, I will live my life for you. Amen. For whoever will call on the name of the Lord will be saved. Romans 10:13 WEB. You can also learn more about how to have a personal relationship with Jesus by reading John 3:1-8 WEB. If you have any questions about this, please let us know.
Now let us pray together for your son's healing:
Dear Heavenly Father,
We come before you in the name of Jesus Christ, lifting up this son to you. We ask, Lord, that you would heal him from the severe headaches, pain all over his body, and numbness in his hands and legs. We know that you are able to do far more abundantly than all that we ask or think, according to the power that works in us. Ephesians 3:20 WEB. We pray for your healing touch upon him, that he may be made whole, and that you would comfort him in his suffering.
We also pray for wisdom and discernment for the doctors and medical professionals treating him, that they would accurately diagnose and effectively treat his condition. Give them insight and understanding beyond their natural abilities, Lord.
In the meantime, we pray that your grace would be sufficient for him, and that your strength would be made perfect in his weakness. 2 Corinthians 12:9 WEB. Help him to endure this trial with patience and faith, trusting in your goodness and sovereignty.
We ask this in the name of Jesus Christ, our Lord and Savior. Amen.
Remember, God's word also tells us:
Beloved, I wish above all things that you may prosper and be in health, even as your soul prospers. 3 John 1:2 WEB
Confess your offenses to one another, and pray for one another, that you may be healed. The insistent prayer of a righteous person is powerfully effective. James 5:16 WEB
Continue to pray for your son, and trust in God's will for his life. Encourage him to put his faith in Jesus Christ, and to draw near to the Lord in this time of need.
