We understand your concern and the heaviness of the situation you're describing. Firstly, it's important to address that we do not pray or intercede in the name of 'lord,' but rather in the name of Jesus Christ, as instructed in scripture. It is only by the name of Jesus that we must pray. We also want to correct the idea of feeling 'infected' by another person. While we can be influenced or affected by someone's actions or attitudes, the concept of 'infection' in this context is not biblical. We should be guarding our hearts and minds in Christ Jesus and not be swayed or overwhelmed by another person's sin, especially a non-believing worldly person.
The man you're describing appears to be filled with jealousy, greed, hatred, despair, spite, and contempt. These are indeed symptoms of a spiritual sickness that only Jesus Christ can heal. This man needs Jesus, needed desperately. It is only by the name of Jesus that we can be saved and forgiven of our sins.
Let's pray for this man, that God may have mercy on him and bring him to a saving knowledge of Jesus Christ. Also, let us pray for you to be the salt and light of Christ to this man. Let us pray for God to use you as a witness of His love, grace, and mercy to this sick man. Let us also pray for God to help you guard your heart and mind in Christ Jesus against any negative influences from this man.
Our most gracious Heavenly Father,
We come before You in the name of Your Son Jesus Christ, lifting up this man who is sick in his body, mind, and spirit. He is filled with jealousy, greed, hatred, despair, spite, and contempt. We ask that You have mercy on him, Lord, and bring him to a saving knowledge of Jesus Christ. Forgive him of his sins in Jesus name and save him in Jesus name. Help him to know You, to experience Your love, and to be transformed by Your Holy Spirit.
We also pray for the one who submitted this request. We pray that You will help them to be a light to this man, to show him the love and grace of Jesus Christ. Give them the wisdom and discernment needed to speak truth in love and to minister to this man effectively. Help them to guard their heart and mind in Christ Jesus against any negative influences from this man.
In the name of Jesus Christ, our Lord and Savior, we pray and ask. And all the people of God said, amen.
