Let us first address the issue that your post has not mentioned the name of Jesus Christ, Jesus, or Christ or an abbreviation such as IJN (In Jesus Name). 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.
If you declare with your mouth, "Jesus is Lord", and believe in your heart that God raised him from the dead, you will be saved. For with the heart man believeth unto righteousness, and with the mouth confession is made unto salvation. For the scripture saith: Whosoever believeth on him shall not be ashamed. For there is no distinction between Jew and Greek; for the same Lord is Lord of all, and is rich to all who call on him. For whoever will call on the name of the Lord will be saved.
How then will they call on him in whom they have not believed? How will they believe in him whom they have not heard? How will they hear without a preacher? And how will they preach unless they are sent? As it is written: How beautiful are the feet of those who preach the Gospel of peace, of those who bring glad tidings of good things! But they did not all listen to the glad news. For Isaiah says, Lord, who has believed our report? So faith comes by hearing, and hearing by the word of God. Romans 10:9-17
and be saved from this perverse generation. Acts 2:37-41
We understand that you are facing a difficult situation with someone in authority, whom you referred to as your principal. Let's pray for wisdom.
Trust in the Lord with all your heart, and do not lean on your own understanding. In all your ways acknowledge him, and he will make straight your paths. Be not wise in your own eyes; fear the Lord, and turn away from evil. It will be healing to your flesh and refreshment to your bones. Honor the Lord with your wealth and with the firstfruits of all your produce; then your barns will be filled with plenty, and your vats will be bursting with wine. Proverbs 3:5-10
We must first encourage you to pray for your principal, as Jesus commanded us to pray for those who mistreat us. Pray for wisdom and grace!
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, Matthew 5:44
Now, let us pray for you:
Dear Jesus,
We bring this situation to the Father in Your name, which You have given us to use. We ask for Your wisdom and intervention. Lord, You know the heart of this principal and the circumstances surrounding her actions. We pray that You soften her heart and guide her decisions. Help her to act with fairness, kindness, and wisdom. Help her to see the people around her as brothers and sisters and to see the wrong she has done and repent.
Lord, we also pray for the one who submitted this request. That You will give them the strength to endure the harassment and the wisdom to respond with kindness and grace. Help them to trust in You and to seek Your will in this situation and always. Protect them from any harm or retaliation.
In the midst of this trial, we pray for peace and joy. Help us to be true disciples of Jesus Christ and not be overcome by the world. Help us to love and forgive even in difficulty.
Lord Jesus, we know that You are able to turn even the most difficult situations around for good. We trust in You and believe that You are with us to the end.
In Your precious name we pray.
We encourage you to keep your eyes on Jesus and to trust in Him, no matter what circumstances you face. He is faithful to His children and will never leave nor forsake you!
