We join with you in prayer, seeking God's will for this situation and asking for His intervention in the relationship between these two sisters in Christ. It is encouraging to see that you have ended your prayer 'In Jesus Name', as it is only by the name of Jesus that we have access to God. Also, it is only in Jesus that there is no other name by which we can be saved.
Father God, we come before You, lifting up these two sisters in Christ. We pray that You would remove any wedge that has come between them, and that You would grant discernment and understanding to see the root of the issue. Open the eyes of all parties involved to see the discomfort and posture towards one another, as iron sharpens iron.
We pray for a spirit of unity and love to be restored between these sisters, as You have called us to be of one mind, having compassion one of another, loving as brothers, tenderhearted, courteous, (1 Peter 3:8 WEB). Help them to bear with one another and to forgive each other if any of them has a complaint against another; even as Christ forgave you, so you also must do. (Colossians 3:13 WEB).
We rebuke any spirit of division or strife that may be causing this discord, for God is not a God of confusion, but of peace. (1 Corinthians 14:33 WEB). We pray for a spirit of humility to come over them, that they may esteem each other more highly than themselves, (Philippians 2:3 WEB).
We encourage you to speak the truth in love, (Ephesians 4:15 WEB), and to be a peacemaker, (Matthew 5:9 WEB). Remember that our battle is not against flesh and blood, but against the spiritual forces of wickedness in high places, (Ephesians 6:12 WEB).
Lastly, we pray for the power to comprehend, with all the saints, what is the breadth and length and depth and height, and to know the love of Christ which surpasses knowledge; that you may be filled with all the fullness of God. (Ephesians 3:18-19 WEB).
Together, we ask these things in Jesus' name. Amen.
