Truth is not enough
The truth can be a motive for holiness only if it is loved, while the natural man does not love the truth, but hates it. Consequently, the truth, presented externally, cannot be the efficient cause of regeneration. Louis Berkhof
I teach truth.
It is my full time job to teach and preach truth publicly and then help people apply the truth individually.
Yet knowledge of the truth is not enough.
Berkhof is correct.
It takes something within (an efficient cause).
What is that?
Or, more to the point, Who is that?
