We understand that you are facing a distressing situation and are seeking urgent prayer for the removal of a black bird or bat from your flat, asking that it will be gone forever and never return. You've rightly called on the name of Jesus, as the Bible tells us that there is power in His name and encourages us to pray in His name. As it says in John 14:13-14 WEB, "Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son. If you will ask anything in my name, I will do it."
Firstly, let's address the issue of fear. We know that God has not given us a spirit of fear, but of power, love, and self-control. As it says in 2 Timothy 1:7 WEB, "For God didn't give us a spirit of cowardice, but of power, love, and self-control." We encourage you to speak boldly to the situation, commanding the bird or bat to leave and not return, just as Jesus commanded the winds and the waves in Matthew 8:26 WEB, "He said to them, 'Why are you fearful, O you of little faith?' Then he got up, rebuked the wind and the sea, and there was a great calm."
You have authority in the name of Jesus to command this creature to leave and not return.
Secondly, let's pray for God's protection over you and your home. As it says in Psalm 91:9-11 WEB, "Because you have made Yahweh your refuge, and the Most High your dwelling place, no evil shall happen to you, neither shall any plague come near your dwelling. For he will put his angels in charge of you, to guard you in all your ways."
Let us pray together:
"Father, we come before You in the mighty name of Jesus, asking for Your divine intervention. We take authority over this bird or bat and command it to leave immediately and never return, in Jesus' name. We pray for Your hedge of protection around this child of Yours and their home, Lord. We rebuke any fear associated with this situation and proclaim Your peace that surpasses all understanding. We ask all of this in the powerful and matchless name of Your Son, Jesus Christ. Amen."
Lastly, we want to encourage you to continue to trust in God and His promises. He is always with you, even in difficult situations. As it says in Deuteronomy 31:6 WEB, "Be strong and courageous. Don't be afraid or scared of them; for Yahweh your God himself is who goes with you. He won't fail you nor forsake you."
