We understand that you are going through a difficult situation, and we are here to pray and provide biblical guidance for you. First, we must address that the request is not in the name of Jesus Christ. It is only by the name of Jesus that we have access to God. There is no other name by which we can be saved. As it is written in Acts 4:12 WEB: "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved!"
Now, let's address the issues you've brought up. You mentioned that a man tried to take your "girl" away and that they tried to take your life's work away. We must first clarify that the Bible teaches that a man and a woman should be joined in holy matrimony, not merely as boyfriend and girlfriend. As Ephesians 5:31 WEB says, "For this cause a man will leave his father and mother, and will be joined to his wife. The two will become one flesh." So we will pray for godly spouses and marriages that honor God.
Concerning the injustice you feel, the Bible tells us that God is a God of justice. As it states in Psalm 103:6 WEB: "Yahweh executes righteous acts, and justice for all who are oppressed.". Vengeance is not ours to take, but God's. As Deuteronomy 32:35 WEB: "Vengeance is mine, and recompense, at the time when their foot slides; for the day of their calamity is at hand, the things that are to come on them shall make haste." So we will pray for God’s justice in your situation.
Regarding the strong language used to describe those who have wronged you, we must remember that Jesus taught us to love our enemies and pray for those who persecute us, as written in Matthew 5:44 WEB: "But I tell you, love your enemies, bless those who curse you, do good to those who hate you, and pray for those who mistreat you and persecute you,". This does not mean we approve of their actions, but rather that we trust God to deal with them justly. Remember it is only by the name of Jesus that we can ask God for help. You mentioned that your communication with your "girl" has been blocked and that you haven't seen her in 18 months. We will pray for a godly resolution to this situation, that if it is God's will, He will restore this relationship in a way that honors Him and that she will be a Christian Believer and agree with the goal of marriage.
Let us pray together:
"Dear Heavenly Father, we come before You in the name of Jesus Christ, lifting up our brother who is going through a difficult time. Lord, we pray for Your justice in his situation, that You would right the wrongs that have been committed against him. We pray that You would soften the hearts of those who have wronged him, and that You would bring them to repentance.
Lord, we also pray for the relationship that has been blocked. If it is Your will, we pray that You would restore this relationship in a way that honors You and that you would have marriage as the goal between Christian Believers. We pray that You would give our brother peace and comfort during this time of waiting and that he do nothing to take vengeance into his own hands.
Finally, Lord, we pray that our brother would find his identity and fulfillment in You alone, and that You would guide him in all righteousness. Lord, we believe that it is only by the name of Jesus Christ that we can be saved and that we can ask God for help. So we pray that you would tell our brother the basic salvation message of believing in Jesus Christ if he has not already done so. We thank You for Your love and faithfulness and accept these requests in Jesus' name. Amen."
May the peace of God, which surpasses all understanding, guard your hearts and your minds in Christ Jesus. Do not let this injustice be a stumbling block in your faith. Continue to walk with God and trust in Him.
