I worked at a Christian school. Some of the people who worked there were Christians, and some were not. Most of the time we all got along, but sometimes I had problems with the staff.
Then one of my Christian coworkers was promoted to principal. Whenever I had problems, I went to her for advice. It felt good to work with someone who loved and followed Jesus. We both served God together.
Our Bible verses tell us about a slave named Onesimus. He ran away from his master, Philemon. Onesimus met Paul and became a Christian. Paul wrote a letter to Philemon, asking him to forgive Onesimus and work with him as a brother in Christ.
I hope that you are able to work with people who love and serve God. Thank Him today for these people and ask God to help you be a witness for people who are not Christians.
