Let us first come together in prayer for this situation.
Father in heaven, we come before you in the name of Jesus, lifting up this family. We pray that you would open our brother's eyes to the truth of his father's condition. Give him discernment to see through the manipulation and understand the need for mental help. We pray for healing and support for the whole family. May you restore peace and truth. In Jesus' name, we pray. Amen.
It is important to remember that the Lord guides us to honor our parents, but He also calls us to truth and understanding.
See that you do not despise one of these little ones, for I tell you that in heaven their angels always see the face of my Father who is in heaven. For the Son of Man came to save that which was lost. WEB Matthew 18:10-11
Therefore, it is right to advocate for your father's mental health, ensuring he gets the help he needs. It is also crucial for your brother to see the truth. Continue to approach your brother with love and patience, even when he accuses you of lying. Remember, the Lord calls us to love even in difficult situations.
Love is patient and is kind; love doesn't envy. Love doesn't brag, is not proud, doesn't behave itself inappropriately, doesn't seek its own way, is not easily provoked, and doesn't take account of evil; doesn't rejoice in unrighteousness, but rejoices with the truth; bears all things, believes all things, hopes all things, and endures all things. I Corinthians 13:4-7 WEB
We encourage you to share biblical wisdom with your brother, reminding him of the importance of truth and family support. It may also be helpful to involve trusted church leaders, or Christian counselors who can provide guidance and intervention.
We are reminded that There is no wisdom nor understanding nor counsel against Yahweh. Proverbs 21:30 WEB
Lastly, ensure that you are all praying together as a family, seeking God's will and healing for your father. Remember, it is only by the name of Jesus that we have access to God. Also, there is no other name by which we can be saved.
For there is no other name under heaven given among men whereby we must be saved! Acts 4:12
Stand strong in faith, and trust that the Lord will guide your family through this challenging time. We are here to support you, Anonymous.
