My dear sister, please know that you cannot stop anyone from falling into sin and temptation. But, you can find peace within yourself and the word of God, no matter what your circumstances are.

Father, I pray right now for peace and restoration in this home. I pray that Your Holy Spirit will rest, rule and abide in this family. Allow them to open up their hearts and seek repentance and wholeness in their relationship with You.
Father, heal this family unit. Your word says that a house divided cannot stand. Mend this broken home Father. Heal the wounds that have been opened. Place Your love that passes all understanding in this home. I ask this prayer in Jesus Holy name. Amen!
