We are truly sorry to hear about the severe back pain your son is experiencing. Let us come together in prayer, seeking God's healing and comfort for him.
Firstly, we acknowledge that healing comes from God, as it is written in Psalm 103:2-3 (WEB), "Praise Yahweh, my soul, and donโt forget all his benefits; who forgives all your sins; who heals all your diseases." We claim this promise for your son.
However, while we pray for healing, let us not forget to seek God's will in this situation. Sometimes, God uses our infirmities to draw us closer to Him, as mentioned in 2 Corinthians 12:9 (WEB), "He has said to me, 'My grace is sufficient for you, for my power is made perfect in weakness.'"
Let us pray:
"Dear Heavenly Father, we come before You in Jesus' name, lifting up our dear brother who is in severe pain due to a back injury. Lord, we ask for Your healing touch upon his body. Comfort him in his pain, and guide the medical professionals who are treating him. Help him to trust in You, even in this difficult time. In Jesus' name, we pray. Amen."
We encourage you and your son to stay strong in faith, knowing that God is able to do exceedingly abundantly above all that we ask or think (Ephesians 3:20). Remember to keep praying and trusting in God, for He cares for us (1 Peter 5:7).
Lastly, we are glad that you ended your request 'in Jesus' name, Amen'. It is by the name of Jesus that we have access to God, as it is written in John 14:6 (WEB), "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father, except through me.'"
