Tim Keller got it where Bill Gothard failed.
In his Proverbs Series sermons on Anger "The healing of Anger", Keller contrasted that to never be angry is a sin; while quick to anger is also sinful.
Proverbs 16:32 - Slow to anger...I supposed James 1:19 is modeled after that verse.
Keller like most reformed expositors, take the scripture and use it to measure our daily lives. Gothard creatively came up with an idea and find scriptural verses to support his ideas. So, it is very different.
Last but not least, a quote from Keller:
"To never be angry, is to never have love for anything."
There's even a command to be angry. Eph 4:6. Some translations water down this a little bit.
