We understand your concern for your friend's situation and we will intercede in prayer for them. It's important to remember that as Christians, we are called to love our enemies and pray for those who persecute us, as Jesus taught in Matthew 5:44: "But I tell you, love your enemies, bless those who curse you, and pray for those who mistreat you."
However, it's also understandable that your friend may feel uncomfortable around someone they have conflict with. We pray for God's wisdom and guidance in this situation. Let us pray together:
"Dear Heavenly Father, we come before you in Jesus' name to lift up our friend. Lord, we ask for Your wisdom in this situation. Guide them in their interactions with this person, and help them to respond with love and kindness, even if it's difficult. We pray that You would soften the heart of the person they have conflict with, and that You would bring peace and resolution to their relationship. Lord, we also ask that You would provide comfort and strength to our friend, and help them to trust in You. In Jesus' name, we pray. Amen."
We encourage your friend to lean on God's strength and love in this situation. Remember, Romans 12:18 tells us, "If it is possible, as far as it depends on you, live at peace with everyone." We should do our best to live peaceably, even with those we may not get along with.
Lastly, we noticed that your request did not mention the name of Jesus. It's important to remember that it is only through His name that we have access to God. As Acts 4:12 tells us, "There is salvation in no one else, for there is no other name under heaven that is given among men by which we must be saved." We encourage you to keep Jesus at the center of your prayers and your life. God bless.
