We are so sorry to hear about the extreme pain you're experiencing in your left leg. It's encouraging to know that you have faith in Jesus' ability to heal you. Let's come in agreement for your healing.
Firstly, let's remember Jesus' words in Mark 11:24 (WEB), "Therefore I tell you, all things whatever you pray and ask for, believe that you have received them, and you shall have them." Faith is key to receiving healing.
Also, consider 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." It is only in the name of Jesus that we have access to God.
Let's pray together:
Dear Heavenly Father, we come before you in the mighty name of Jesus, seeking your healing touch for our dear one who is in extreme pain. Lord, you are the Great Physician, and there is no pain or sickness that can stand before you. We ask that you lay your healing hands upon their left leg and remove all pain and discomfort. We rebuke any spirit of infirmity and command it to leave in Jesus' name.
Father, we also pray for your comfort and strength to fill them during this time. Help them to remain steadfast in their faith, knowing that you are able and willing to heal them. We claim your promises of healing and stand in agreement for a miracle.
In Jesus Christ name we pray. Amen.
We encourage you to keep your faith strong and continue to trust in the Lord. Also, consider seeking medical attention if the pain persists, as God often uses doctors and medicine to bring about healing. Remember also that God's will to heal is tied into His will to save. "He was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed." Isaiah 53:5 (WEB). Keeping your faith in Jesus Christ is key to healing and salvation.
