We understand your concern and are here to pray with you and provide guidance. Firstly, let's bring your situation to God in prayer.
Father in heaven, You are our refuge and our fortress. We come before You in Jesus' name to seek Your protection and guidance for our brother/sister. They feel unsafe and vulnerable due to suspicious activities around their home. We pray that You will surround their dwelling with Your angels, and that any plot or scheme against them will be thwarted. We know that "No weapon that is formed against you will prosper" Isaiah 54:17
In addition, Psalms 3:3 says "But you, LORD, are a shield around me, my glory, and the one who lifts up my head." We pray that you would provide a supernatural shield of protection so that no person with ill intentions will be able to harm or disturb them. We also ask for Your wisdom and discernment to guide them in this situation. Help them to know the truth about any activity in their attic and to take appropriate actions to ensure their safety. We know that "For God has not given us a spirit of fear, but of power, love, and self-control." 2 Timothy 1:7 Please help them deal with this situation with no fear.
In Jesus name Amen.
Now, let's address your concerns. It's important to ensure your safety and peace of mind. First, try to gather more information about the situation. Is there any way you can safely investigate or confirm your suspicions? If necessary, consider involving local authorities or your landlord. They can provide assistance and support. It is likely whoever is entering the attic has no idea you are even there and does not know you are living there.
The Bible tells us "Let every soul be in subjection to the higher authorities, for there is no authority except from God, and those who exist are ordained by God." Rom 13:1 and "For rulers are not a terror to the good work, but to the evil. Do you desire to have no fear of the authority? Do that which is good, and you will have praise from the authority Romans 13:3
Finally, remember that God is your ultimate protector. Rest in His promises, knowing that He is in control. Continue to pray for peace and safety and ask God to show you how to best proceed. He promises "I will say of the LORD, He is my refuge and my fortress; my God, in whom I trust.'" Psalms 91:2
We are here for you, and we will continue to pray for your safety and peace of mind. Keep trusting in the Lord, and He will guide you through this challenging time.
