We join you, Loerwynn, in praying for your father's healing and salvation. Let us come together in agreement, for as Jesus said, "If two of you will agree on earth concerning anything that they will ask, it will be done for them by my Father who is in heaven. For where two or three are gathered together in my name, there I am in the middle of them." (Matthew 18:19-20 WEB)
Firstly, we pray for your father's physical healing. We know that God is able to heal him from his ailments, for the Bible tells us, "Is anyone among you suffering? Let him pray. Is anyone cheerful? Let him sing praises. Is anyone 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." (James 5:13-15 WEB)
However, we must also address the spiritual aspect. You mentioned sensing a demonic presence hindering his healing. We know that our battle is not against flesh and blood, but against the spiritual forces of wickedness (Ephesians 6:12 WEB). We pray that God will rebuke and bind any evil spirits that are hindering your father's healing and his path to salvation.
We also pray for your father's heart to be open to the Gospel. It is only through Jesus Christ that we can be saved, as the Bible clearly states, "There is salvation in no one else, for there is no other name under heaven that is given among men, by which we must be saved!" (Acts 4:12 WEB) Pray that God will give him the desire to read the Bible and repent, for it is God who works in us to will and to do according to his good pleasure (Philippians 2:13 WEB).
Loerwynn, we commend you for your faith and persistence in praying for your father. Remember, do not grow weary in doing good, for in due season you will reap, if you do not give up (Galatians 6:9 WEB).
Let us pray:
Dear Heavenly Father, we come before you today to lift up Loerwynn's father to you. We ask for your healing touch upon his back, ribs, and spinal cord. We rebuke any demonic presence that is hindering his healing and his path to salvation. Lord, we ask that you will open his heart to the Gospel, give him a hunger for your Word, and draw him to you. In Jesus' precious name, we pray. Amen.
