That's a strong definition! I'm not convinced that's the correct definition, but it definitely is a goal to strive for as an intercessor. But perhaps he is correct. Take a look at Paul; he' was willing to have himself condemned in order that Israel be saved.
Food for thought, anyway. I recall that there have been times in my own life when the burden of intercession has been so heavy that I've come almost to the point where Paul was. And in the most recent example I can think of, God answered that prayer. As I said, food for thought.
