Let's bring this matter to the Lord in prayer, seeking His divine intervention and guidance. We commend you for standing on the side of truth and righteousness, even in the face of adversity.
Firstly, let's address the workplace dynamics you're facing. We are reminded in Colossians 3:23-24 WEB, "Whatever you do, work heartily, as for the Lord, and not for men, knowing that from the Lord you will receive the inheritance as your reward. You serve the Lord Christ." Even when others are not acting with integrity, we are called to maintain our own, trusting that God sees our faithfulness.
Regarding the threats and harsh words from your senior manager, we recall the words of Jesus in Matthew 5:11-12 WEB, "Blessed are you when people reproach you, persecute you, and say all kinds of evil against you falsely, for my sake. Rejoice, and be exceedingly glad, for great is your reward in heaven. For that is how they persecuted the prophets who were before you." It is important to note that we should not seek out persecution, but this issue is obviously being faced. Consider this, it is better to be persecuted for righteousness than for evil. Persecution can also be a sign of spiritual maturity.
We pray that God will protect you from those who seek to harm you and guide your super senior manager to act with fairness and wisdom. "He who conceals hatred has lying lips, And he who utters a slander is a fool. Do not be a witness against your neighbor without cause. Do not deceive with your lips. Do not say, 'I will do to him as he has done to me; I will repay the man according to his work.'" Proverbs 24:28-29, Proverbs 20:22 WEB. We ask God not to allow people with bad intentions to harm you.
We also pray for the transfer of those who are acting unfairly, as you requested. However, we must remember that our ultimate trust is in God, not in the removal of difficult people. "For we do not wrestle against flesh and blood, but against the principalities, against the powers, against the world’s rulers of the darkness of this age, and against the spiritual forces of wickedness in the heavenly places." Ephesians 6:12.
Finally, we encourage you to continue to act with integrity and love, even towards those who are treating you unfairly and hostilely, as we are reminded of Jesus said in Matthew 5:44 WEB, "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,". Pray to God for their salvation in Jesus Christ.
Let us pray together.
"Father in heaven, we come before You in Jesus' name, lifting up our brother/sister who is facing adversity in the workplace. We ask for Your protection and guidance. Please intervene and guide their super senior manager to act with fairness and wisdom. We pray God Your will be done with the situation. We ask that You would remove those who are acting unfairly, and work in the hearts of those who are being hostile. Help our brother/sister to continue to act with integrity and love, even in the face of adversity. We trust in You, Almighty Lord Jesus Christ. Amen."
We encourage you to continue to pray and seek God's will in this situation, always acting with love and integrity. God promises to fight for us when we take our stand on His word. Be strong and courageous.
