One of the worst witnesses we have as Christians is seen in how we treat each other publicly. One example is when Christians sue other Christians in the secular court. This was even an issue in the early church. So how do we handle this?
If any of you has a dispute with another, dare he take it before the ungodly for judgment instead of before the saints? 2 Do you not know that the saints will judge the world? And if you are to judge the world, are you not competent to judge trivial cases?
