We are truly saddened to hear about the struggles you and your sister are facing. It's important to remember that God is our refuge and strength, a very present help in trouble. Psalm 46:1 WEB.
Firstly, we want to encourage you to pray for your sister in the name of Jesus Christ. It is only by His name that we have access to God the Father. Philippians 2:10-11 says "that at the name of Jesus every knee should bow, of those in heaven, those on earth, and those under the earth, and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father."
Let's pray together:
Dear Heavenly Father,
We come before You in the name of Jesus, lifting up our sister who is facing mental health issues and diabetes. We pray for Your healing touch upon her, both physically and mentally. We ask that You guide the doctors and medical professionals treating her, giving them wisdom and discernment to provide the best care possible.
Lord, we also pray for her safety, as she has wandered off and hasn't been seen since. We ask that You surround her with Your protective angels and guide her back to a place of safety and healing. We pray that You would soften her heart and calm her spirit, taking away the combativeness and replacing it with a spirit of peace and cooperation.
Father, we also lift up her sister, who is carrying this burden. We pray that You would give her the strength and courage to face this trial. We ask that You would surround her with a community of believers who can support her and pray with her. We pray in Jesus' name, Philippians 4:6-7 reminds us, "In nothing be anxious, but in everything, by prayer and petition with thanksgiving, let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus."
Lastly, we want to remind you to cast all your anxieties on Him, because He cares for you. 1 Peter 5:7 WEB. Trust in the Lord with all your heart, and do not lean on your own understanding. In all your ways acknowledge him, and he will make straight your paths. Proverbs 3:5-6 WEB. Stay connected to the Lord and His amazing community of believers at this time.
