When a COG minister ask us to “speak life” what does he mean? That is a common cliche we hear often however what does it mean? Is there a negative connotation implied?

Is this a new form of Peale and Shuyler positive thinking? Is it new thought speech?

Can you “speak life” without speaking death to some one? Isn’t this speech control for church growth strategies?
