We are truly sorry to hear about your auntie's condition. The importance of agreement in prayer is stressed in the Bible using the example of a family having the problems of the flesh, we too can focus on the problem or seek God's intervening hand together. KJV's Matthew 18:19 Jesus said, "that if two of you shall agree on earth as touching any thing that they shall ask, it shall be done for them of my Father which is in heaven." We too need to to agree in prayer with the sister in difficulty.
First, let us echo your faith and trust in God's divine healing power. In Jesus is life eternal and healing from God himself and that "by his stripes we are healed" From Isaiah 53:5 In Psalm 103:2-3, it is written, "Bless the Lord, my soul, and do not forget our God's benefits. Who is forgiving all your iniquities, is healing all your diseases" Your aunt needs to be cleansed and forgiven of her sins. But by his knowledge shall my righteous servant justify many; for he shall bear their iniquities of Isaiah 53:11.
Let us pray together:
"Father in heaven, we come before You in the mighty name of Jesus Christ, seeking Your divine intervention in Jurbak's auntie's life. And the prayer of faith shall save the sick, and the Lord shall raise him up; and if he has committed sins, they shall be forgiven to him.. You are the Great Physician, and by the stripes of Jesus, we claim healing for her. If Jurbak's auntie's is praying and confessing and receiving Jesus by faith, we claim complete salvation and mercy for her. Touch her, Lord, with Your healing power. Comfort her. Strengthen her. You did not create us to be ill but whole. While we are asking for the infirmities to be removed, there may be non-physical infirmities to need to be addressed. Do we need any spiritual surgery. If spiritual things are much more important than physical ones. Guide and direct the medical team caring for her according to your will. She will not just survive but thrive with salvation Jesus. In Jesus' name, we come before you to ask all this. Hear our prayer, Oh God. for we ask in faith through unquestioning reliance on thee. With affirmation of healing resulting from your curing of her. In Jesus Christ's name, we pray, and in confidence of the receipt of this request, Amen."
Please let us know that Jurbak and his auntie confess Jesus as Lord. It is important for the salvation of souls and the answer of this. Make we sure we are not praying for the audience of the Jews, rather for the propitiation of sins in Jesus with the receipt of this, salvation according to Acts 4:12 and Romans 10:9. If any of the foregoing is incomplete, please make your requests known. This is very important.
