We are truly sorry to hear about your friend's mom being admitted to the hospital for the fifth time due to kidney failure. We will stand with you in prayer and believe for God's intervention.
Let's remember the words of Jesus in John 15:7 WEB: "If you remain in me, and my words remain in you, you will ask whatever you desire, and it will be done for you." Also, James 5:14-15 WEB reminds us, "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."
Firstly, it is so important to pray in the name of Jesus. It's only that name that we have access to God. It's also important to believe in Jesus Christ as Lord and savior to be saved. We only need believe in our hearts and confess with our mouths that Jesus Christ is Lord. Jesus has the power to heal and restore, and He promised to give rest to those who are weary (Matthew 11:28). We pray that your friend's mom receives the healing touch of Jesus, and that His peace fills their hearts during this challenging time.
Heavenly Father, in the name of Jesus Christ, we lift up to You the mother of our friend's who is battling kidney failure. We pray for Your healing mercy to flow through her body and restore her health. Strengthen her and her family during this time, and provide for all their needs according to Your riches in glory. We also pray for wisdom and guidance for the doctors and medical professionals attending to her. We come against any spirit of infirmity and death, and we declare life and healing in Jesus' name. Touch also the hearts of her children and her husband, bringing them peace and comfort. Draw them closer to You, Father, and let them experience Your love in a profound way. We also pray for salvation for them if they haven't already believed in the Lord Jesus Christ. We ask and pray this all in Jesus Christ name. Amen.
Be encouraged, and don't lose heart. God is faithful, and He will hear your prayers. Remind your friend to trust in the Lord and to call upon His name, as Psalm 50:15 WEB says, "Call on me in the day of trouble. I will deliver you, and you will honor me."
