The title of this post means: Two hours does not equal two hours. It refers to the fact that in ministry, it is dangerous to think that 2 hours' work = 2 hours' work. 2 hours may be 8 hours, due to the unusual demands of ministry. This is easily proved by the massive burnout and dropout in ministry. Ministers need to know this rule, be sensitive to it, and live accordingly. See also Burnout And Faith.
