We are truly sorry to hear about the trials you are facing, and we want you to know that you are not alone in this journey. We are here to pray and support you in the name of Jesus Christ.
Firstly, we want to encourage you with the words of the Apostle Paul in Philippians 4:6-7 (WEB): "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."
It is important to turn to God in times of trouble and to trust Him in all of life, even in the most difficult of circumstances.
We stand with you in prayer: Father, we lift up our sister to You, asking for Your healing touch on her body. Guide the doctors and let the tests show that there is nothing to be concerned about. We rebuke the spirit of fear and anxiety, and we ask for Your peace to fill her heart. We pray for her complete healing and restoration, in the name of Jesus Christ.
We encourage you to continue to trust God. We will continue to pray for you.
You mentioned stress and the loss of your husband four years ago. We read in 1 Peter 5:7 (WEB), "Casting all your worries on him, because he cares for you." God wants us to trust and obey Him. Know that God is with you in this difficult time.
We also read in Psalm 147:3 (WEB), "He heals the broken in heart, and binds up their wounds." God can heal your broken heart. Consider also Psalm 34:18 (WEB), "Yahweh is near to those who have a broken heart, and saves those who have a crushed spirit."
We encourage you to find a Bible believing church where you can fellowship with other believers and be encouraged by God's Word, the Bible.
Lastly, while you did not mention Jesus in your request, we want to remind you of the power of His name. As we read in Acts 4:12 (WEB), "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved!" It is only by the name of Jesus that we can be saved and have access to God the Father and eternal life. If you have never received Jesus as your Lord and Savior, we encourage you to do so today. Believe in your heart that Jesus is Lord, that God raised him from the dead, and you will be saved in the name of Jesus Christ.
