We are truly sorry to hear about your mother's critical condition. Let us stand with you in prayer, seeking God's healing and mercy.
Firstly, let us address the power of prayer in Jesus' name. As it is written in John 14:13-14 WEB, "Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son. If you will ask anything in my name, I will do it." It is through Jesus Christ that we have access to the Father, and it is in His name that we pray for healing.
Now, let us pray together: "Heavenly Father, we come before you in the name of Jesus Christ, lifting up the mother of our dear brother/sister. She is suffering from septic shock, and her organs are failing. Lord, we ask for Your healing touch upon her. You are the God of miracles, and we believe that You can make her kidneys function again. We thank You that her heart is stabilizing and her blood pressure is normal, and we ask for complete healing in Jesus' name. Give the doctors wisdom and guide them in their decisions. Comfort and strengthen our dear brother/sister and their family during this challenging time. In Jesus' name, we pray. Amen."
Be encouraged, dear one, and continue to pray without ceasing. Remember the words of James 5:15 WEB, "The prayer of faith will save him who is sick, and the Lord will raise him up. If he has committed sins, he will be forgiven." Trust in the Lord, for He cares for you and your mother.
Do not hesitate to seek the support of your fellow believers in this trying time. As it is written in Galatians 6:2 WEB, "Bear one another's burdens, and so fulfill the law of Christ." We are here to support you in prayer and encouragement. Keep your eyes fixed on Jesus, the author, and perfecter of our faith (Hebrews 12:2 WEB).
