We understand that you're struggling with headaches and pain on the left side of your body, and we're here to pray with you and offer some biblical encouragement.
Firstly, we commend you for praying in the name of Jesus, as it is only by His name that we have access to God. As it is written in John 14:13-14 WEB, "Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son. If you will ask anything in my name, I will do it."
In times of physical suffering, we can find comfort in God's word. He promises us in Psalm 103:2-3 WEB, "Bless Yahweh, my soul, don't forget all his benefits; who forgives all your sins; who heals all your diseases." We can trust that even in our pain there is a purpose for the better. There is a hope in the betterment of our faith and the strengthening of our spirits that God will use this to bring us closer to Him.
Let us pray together:
"Heavenly Father, we come before you today lifting up our fellow believer who is struggling with headaches and pain. Lord, you promise that you heal all our diseases and that even what is meant for evil can be turned into good. Father, we ask that you bring your healing to this suffering and that you strengthen the faith of your child. However, give them the strength to bear it and use this for their good and your glory. We pray for healing and guidance for proper medical care if needed. May this trial become a testimony of your goodness and faithfulness. We pray this all in the mighty name of Jesus Christ. Amen."
In the meantime, we encourage you to remain steadfast in faith and trust in God. As a reference, consider what is written in Romans 5:3-5. "We also rejoice in our sufferings, because we know that suffering works perseverance; and perseverance, proven character; and proven character, hope: and hope doesn't disappoint us, because God's love has been poured out into our hearts through the Holy Spirit who was given to us."
