We understand the gravity of your situation and we stand with you in prayer, seeking God's protection and intervention. Let us first remember the words of Psalm 34:18, "Yahweh is near to those who have a broken heart, and saves those who have a contrite spirit."
We pray, dear Heavenly Father, in the name of Jesus Christ, for Your divine protection over this individual and their family. As they must attend this meeting, surround them with Your angels to guard and guide them. As the psalmist declared, "He will hide me in the shelter of his tabernacle. He will lift me up on a rock." (Psalm 27:5)
We rebuke the plans of the evil one to cause harm and destruction. As it is written, "No weapon that is formed against you will prosper; and every tongue that accuses you in judgment you will condemn." (Isaiah 54:17) We pray that these criminals will be brought to justice and their evil deeds exposed, "For there is nothing hidden, except that it should be made known; neither was anything made secret, but that it should come to light." (Mark 4:22)
We also pray for the removal of these suspicious networks and any malicious software from the computer and family. May God's wisdom guide in cleansing these devices, "But wisdom is justified by all her children." (Luke 7:35)
Lastly, we remind you to cast all your anxieties on Him, because He cares for you. (1 Peter 5:7) Trust in His ability to deliver you from this situation. We also encourage you to involve local authorities if you haven't already, for they are God's ministers for good. (Romans 13:4)
We noticed that your request does not mention the name of Jesus Christ. It is only by His name that we have access to God, "For 'whoever will call on the name of the Lord will be saved.'" (Romans 10:13) We encourage you to put your trust in Jesus, for there is no other name under heaven given among men whereby we must be saved. (Acts 4:12)
We continue to pray for your safety, deliverance, and salvation, in Jesus' name. Amen.
