We understand that you are seeking God's protection for your siblings and deliverance from evil dreams. It's important to remember that our help comes from the Lord, who made heaven and earth (Psalm 121:2, WEB).
Firstly, we notice that your prayer is addressed to the Heavenly Father, but it is essential to pray in Jesus' name. As Jesus said, "Most certainly I tell you, whatever you may ask of the Father in my name, he will give it to you. Until now, you have asked nothing in my name. Ask, and you will receive, that your joy may be made full" (John 16:23-24, WEB). It is through Jesus Christ that we have access to God, and there is no other name by which we can be saved (Acts 4:12, WEB).
Now, let us pray together for your siblings and your peace of mind:
Heavenly Father, we come before You in the name of Jesus Christ, lifting up Cyrwach and their siblings. We commit them to Your care, trusting in Your promise to care for the orphans and be a father to the fatherless (Psalm 10:14, WEB). We pray that You will surround them with Your favor as with a shield and that no weapon formed against them shall prosper (Psalm 5:12, Isaiah 54:17, WEB).
We rebuke the evil dreams that Cyrwach has been experiencing, for God has not given us a spirit of fear, but of power, love, and self-control (2 Timothy 1:7, WEB). We claim the promise that You will give Your angels charge over them, to keep them in all their ways (Psalm 91:11, WEB).
Lastly, Father, we pray for Cyrwach's peace of mind. We ask that You will grant them the peace that surpasses all understanding, guarding their heart and mind in Christ Jesus (Philippians 4:7, WEB). Help them to cast all their anxieties on You, because You care for them (1 Peter 5:7, WEB).
In Jesus' name, we pray. Amen.
Be encouraged, Cyrwach, for God cares for you and your siblings more than you can imagine. Trust in Him, and He will act on your behalf. Remember the words of Jesus, "Ask, and it will be given you. Seek, and you will find. Knock, and it will be opened for you" (Matthew 7:7, WEB). Keep praying and seeking God's will for your life and your siblings.
