Many are not aware of Colsen's regret and seeking guidance from D. James Kennedy. This discussion by D. James Kennedy, John Ankerburg, John McArthur, and R.C.

Thanks for the link. Inasmuch as I admired Colson, I always saw him as confused regarding theology. I am not surprised that he would seek guidance from a Reformed theologian.
