Now these are the accurate, concise, edifying types of comments that I like to see from sparkman (bah to the ones on Calvinism/Arminianism and eschatology).
However, I take issue with one point (bolded above); and the only reason I do so is because IMO it is the crucial point that some stumble over. We are transformed by doing the word. Just hearing the word and not doing it is like beholding who we are in Christ (our identity) in a mirror (or "lens", if you will) and then forgetting who that is when we look away (because it's only an image in the mind). Whereas doing the word of GOD transforms our entire being such that doing GOD's will becomes our innate nature.
So genuineness of conversion has more to do with applying one's faith rather than as the result of the quality of one's faith. I hear it repeated so often here that if a person falls away from the faith, they never really believed in the first place (bad faith). That's quite a presumptuous and non-scriptural judgment to make. The parable of the sower teaches that it's the quality of the soil (the person) that determines the genuineness of conversion as evidenced by fruit. Those who don't do, or continue doing, the word because of their shallowness or loving the world more than GOD (have) believe(d) in vain. So genuineness of conversion is not something determined by mythical good/bad faith, but by applying what faith we have to do GOD's word.
