We understand your distress, Kensem, and we are here to intercede on your behalf. Let's bring your situation before the Lord, seeking His peace, protection, and intervention.
Firstly, we are reminded of Psalm 5:1-3 in the World English Bible (WEB): "Give ear to my words, Yahweh. Consider my meditation. Listen to the voice of my cry, my King and my God; for to you do I pray. Yahweh, in the morning you shall hear my voice. In the morning I will lay my requests before you, and will watch expectantly."
We should always bring our concerns to God, trusting that He hears us. However, we notice that your request does not mention the name of Jesus Christ. It is by His name that we have access to God, as it is written in John 14:6, "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father except through me.'" Therefore, we will pray in His name and encourage you to do the same.
Now, let us address the issue with your landlord's assistant. We are instructed in Romans 12:17-18, "Don’t repay anyone evil for evil. Consider what is good from the sight of all men. If it is possible, as much as it is up to you, be at peace with all men." While we pray for the exposure of their dishonesty, we should also pray for their conviction and repentance.
Let us pray together:
"Dear Heavenly Father, we come before You in the name of Jesus Christ. We lift up Kensem to You, seeking Your peace and protection in their life. Lord, You know the struggles they are facing with their landlord's assistant. We ask that You shine Your light on this situation, exposing any wrongdoing, and bring it to an end. Provide Kensem with a supernatural way out of this situation, according to Your will. At the same time, Father, we pray for the assistant, that they may be convicted of their actions and turn towards righteousness. We ask all these things in Jesus' name, amen."
Stay strong in your faith, Kensem, and continue to bring your concerns to God, trusting in His power and love.
