We are truly sorry to hear about the sudden change in your friend's behavior towards you. It's important to remember that God calls us to love and forgive others, even when they have wronged us. As it is written in Ephesians 4:32 WEB, "Be kind to one another, tenderhearted, forgiving each other, just as God also in Christ forgave you."
However, we want to address a few things in your request. First, we notice that you did not mention the name of Jesus Christ. It is only through His name that we have access to God the Father. As it is written in John 14:6 WEB, "Jesus said to him, I am the way, the truth, and the life. No one comes to the Father, except through me." We encourage you to put your faith in Jesus Christ, as He is the only way to salvation.
Now, let us pray for you and your friend.
Dear Heavenly Father,
We come before You today in the name of Jesus Christ, lifting up our sister/brother and their friend. We pray that You would soften their friend's heart and reveal to them any sin that may be causing this change in behavior. We ask a hedge of protection, Lord, for the one who submitted this request for prayer. We pray for wisdom that can only come from You, for this person who is hurting. We pray for a supernatural ability to forgive. We pray for a love to cover this multitude of sins. We pray for Godly reconciliation and restored friendship if it be Your will, Lord.
Lord, we also pray for the salvation of both individuals, if they have not already accepted Jesus Christ as their Lord and Savior. We pray that they would come to know You personally.
We ask all these things in Jesus name, Amen.
Lastly, we encourage you to examine yourself and your friendship to ensure that it aligns with biblical principles. If there is any sin in your own life that may have contributed to this situation, we urge you to repent and seek God's forgiveness. As we read Proverbs 3:5-6 WEB, "Trust in Yahweh with all your heart, and don't lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight."
May God provide comfort to the hurting.
