Matthew 7:16, 12:33 and various verses give the only test there is for the merit of any god-talk; fruit.
All other commentary is about knowing through scripture — yet give no means to know how to unearth good exegesis or hermeneutics — and then by familiarity with God’s character. But these all hang on knowing or recognizing the good.
What does that imply but that God is synonymous with the good, that we are enabled by nature or by grace to know what the good is, and, that though there are many interpretations and applications of scripture, the good of scripture isn’t in correct interpretation but instead, that how we interpret it must lead us toward the good and into deeper understanding of it and into participation with it?
Just a thought.
