Negative Speaking

I have a struggle with this issue of calling people who spoke out the immoral behaviors and abuses of leadership as being negative. Just this morning, I read a post from a LC with a quote from Witness Lee.

"Positive listening will rescue us from negative listening. If we listen to God's word from morning to evening, we will not have an ear to listen to any negative speaking. Negative talk prevails in the church life because certain ones turn their ears from God to something else. These ones do not speak Christ, the word of God, grace, or the gospel. Instead they listen to negative things, and they work and move according to the negative things they hear. The result is the spreading of death. If we turn our ears from other things back to God Himself, there will not be any problems, and only life will be spreading, not death." (Life-study of Leviticus, Msg. 30)
