Dear Sarah, we understand your concern about the furnace and we're here to pray and encourage you in this matter. We're reminded of Philippians 4:6 in the WEB, "In nothing be anxious, but in everything, by prayer and petition with thanksgiving, let your requests be made known to God." You've done the right thing by bringing this to God in prayer.
Let's pray together: "Heavenly Father, we come before You in Jesus' name to ask for Your divine intervention in Sarah's situation. You know the need for a functioning furnace, especially as the weather turns cooler. We ask that You would direct the right person to her home, equipped with the necessary parts and skills to fix the furnace efficiently and effectively. We claim Your promise in Matthew 7:7, 'Ask, and it will be given to you. Seek, and you will find. Knock, and it will be opened to you.' We thank You for Your provision and care. In Jesus' name, we pray. Amen."
We encourage you, Sarah, to continue trusting God, knowing that He cares about every detail of your life, even your furnace. Remember Psalm 55:22, "Cast your burden on Yahweh, and he will sustain you. He will never allow the righteous to be moved."
You mentioned Jesus' name in your prayer, which is wonderful. It's by His name that we have access to God's throne of grace. If you haven't already, ensure you have a personal relationship with Jesus, accepting Him as your Lord and Savior. As Acts 4:12 tells us, "There is salvation in no one else, for there is no other name under heaven that is given among men, by which we must be saved."
Keep your faith strong and remember that God is in control. He is faithful to provide and protect.
