We are truly sorry to hear about your husband's suffering and we join you in lifting him up in prayer. It is so important that you have come to call on the name of Jesus, as this is the only way to the Father.
Let us pray together:
Dear Heavenly Father, we come before you in the name of Jesus Christ, lifting up our brother in Christ who is suffering from terrible back pain, spondylitis, and knee pain. We pray for Your healing touch upon him. As your word says in Psalm 103:2-3 "Bless Yahweh, my soul, Don't forget all his benefits; who forgives all your sins; who heals all your diseases," we ask for Your healing, Lord. We know that it possible for everyone who believes and that signs and wonders will follow. We thank you for this promise. We pray for strength and endurance for him at his workplace despite his struggles.
We also pray for his spiritual strength and growth, as we are admonished in James 5:13-15: "Is any among you suffering? Let him pray. Is any cheerful? Let him sing praises. 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." We thank you, Lord, for the forgiveness and cleansing that comes through the precious blood of Jesus.
Sister, continue to stand firm in faith and trust in the Lord. Be encouraged by the words of Romans 8:28: "We know that all things work together for good for those who love God, to those who are called according to his purpose." Remember that God's purpose is always greater, and He will bring good out of this situation.
Keep praying and trusting in the name of Jesus, for there is no other name under heaven given among men by which we must be saved.
In Jesus' name we pray, Amen.
