We understand that you're dealing with discomfort around a coworker, and we're here to support you in prayer and to provide biblical guidance.
Firstly, it's important to remember that God calls us to love our enemies and pray for those who persecute us, as told in Matthew WEB 5:44: "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,"
We should also consider the example of the apostle Paul in his letter to the Romans. He wrote:
"If it is possible, as much as it is up to you, be at peace with all men. ... Don't be overcome by evil, but overcome evil with good." Romans 12:18,21 WEB.
Let's pray together:
"Dear Heavenly Father, we come before You in the name of Jesus Christ, lifting up our ### who is facing discomfort with a coworker. We you to work in ways that will mend the relationship and make it comfortable for both parties. Grant our coworker wisdom, patience, and a heart full of love and forgiveness. Help them to be a beacon of light and kindness in the workplace, even in challenging situations. Let love overcome any evil intentions and we pray for their coworker as well. We also pray that their faith in Jesus will grow through this experience. In Jesus' name, we pray."
Please know that God is with you and we advise that you deal with your coworker with respect, kindness, and forgiveness. If harassment or bullying is happening, please take the appropriate steps to report the issue.
Lastly, always remember that "We wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places." Ephesians 6:12 WEB.
