Exchanging Insults

During the course of an (entertaining) interview about what books he's currently reading, Carl Trueman made the point about his non-use of Twitter,

I do not believe Jesus wants me to use my remaining years in exchanging insults with other Christians.

adding, more positively,

I think he wants all his people to witness to the world by using the time and talents he has given them to edify the body of Christ and to help the rising generation think clearly about the challenges we all face.

I can go with that.
