We understand that you're dealing with a difficult situation, and we're here to support you in prayer and truth. We need to remember that God cares about our relationships and wants what is best for us.
Firstly, it's important to acknowledge that the behavior of this person is the real issue and not necessarily the person themselves.
In 1 Corinthians 15:33 WEB it says
Do not be deceived! "Evil companionships corrupt good morals."
1 Peter 5:8 WEB tells us:
Be sober and self-controlled. Be watchful. Your adversary, the devil, walks around like a roaring lion, seeking whom he may devour.
It is wise to be aware of those who may be harmful to us, and it's important to create boundaries to protect ourselves. However, we should also remember that God desires for all to be saved and come to the knowledge of the truth.
In Matthew 5:44 WEB, Jesus tells us:
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,
You may choose to distance yourself from this person, but also consider praying for their well-being and salvation. Pray that God would work in their life and transform them. Let's pray together:
Dear Heavenly Father,
We come before you in the name of Jesus, lifting up our brother/sister who is dealing with a difficult relationship. Lord, you know the details of this situation, and we ask for your wisdom and guidance in handling it.
Father help them to establish healthy boundaries and protect them from any harm. We also pray for the individual who is causing distress. Lord, you desire for all to come to repentance and faith in Jesus. Work in their life, soften their heart, and draw them to yourself.
Help us to remember that even when someone is difficult, they are still made in your image and valuable to you. Give us your love for them and your wisdom in dealing with them. We ask all these in the precious name of Jesus Christ our Lord, Amen.
