A while back I blogged that I'm done arguing. This does not mean that I'll not counter false teaching about the gospel. It does mean that I'm not going to argue with other Christians about secondary issues. I'll talk about them, but no more arguing.
I came to this decision because I realized (finally) that silence does not equal agreement. Just because I don't counter what I hear, it does not automatically mean that I agree with what I've heard. I don't know why it's taken me almost 42 years to come to this conclusion.
As Christians we know we must stand for the truth of the gospel. The problem is that we also tend to think that we must stand for the truth of whatever it is that we believe about church structure, leadership, creation, education, women's roles, the meaning of the Lord's Supper, the form of the Lord's Supper, baptism, etc., etc.
Everything does not have to be argued nor should it be. When we are silent, this does not mean we've lost, caved in, or surrendered. It simply indicates that we aren't going to discuss the topic anymore at that time with that person. Since it takes two to argue, that stops it cold.
My advice to you is to pick your arguments very carefully. They can often lead to unnecessary division within the church. Instead, try being quiet. I've enjoyed it so far.
