Onesimus was a slave in the first century world. In fact, he was a runaway slave. A crime that was punishable by death if the owner wished it so. But while he was running away from his owner, Onesimus met Paul and became a Christian. In doing so, his life was completely changed. Becoming a Christian causes change in the lives of people. And when we look at Christians, we need to look past their sins committed before coming to Christ, and instead see the new creation Christ has made them.
