We are truly sorry to hear about your husband's pain and discomfort. We stand with you in prayer, believing in God's power to heal and restore. Let us remember God's word 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."
Heavenly Father, we come before You in the name of Jesus Christ, lifting up our dear sister's husband. You know his pain and discomfort, Lord, and You are the Great Physician. We pray for Your healing touch upon him. Ease his back pain, heal his spondylitis, and mend his knees. In the name of Jesus, we rebuke the spirit of infirmity and command it to leave his body. Lord, strengthen his faith and give him patience in this trial. Encourage his heart and help him to endure. We thank You, Lord, for Your mighty hand that heals, and we glorify Your holy name. In Jesus' name, we pray.
We encourage you both to hold onto faith and hope. Remember the words of Jesus 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." Keep praying and believing, for with God, all things are possible.
We also encourage you to seek godly medical advice and treatment, trusting that the Lord can work through doctors and medicine to bring about healing. Continue to stand on God's word and trust in His goodness. We are here with you in spirit, agreeing with you in prayer.
