For I bear the Jews witness that they have a zeal for God, but not according to knowledge.
Romans 10:2

Like so many Christians who love a God and Messiah whom they barely even know. They refuse to learn God’s commandments because they believe the Spirit will lead them into all truth, and when the Spirit continually leads them back to the truth of Torah, they continually silence him because they have already decided that the Spirit is antithetical to the Word.

A zeal for God isn't enough if it doesn't include obedience to his actual commands, which are an extension of his character, as opposed to what we wish his commands had been, based on a faulty idea of who he is.
