Can't Teach A Drunkard

The possuk (14:21) says  וַיִּֽירְא֥וּ הָעָ֖ם אֶת־י״י֑ וַיַּֽאֲמִ֙ינוּ֙ בַּֽי״י֔ וּבְמֹשֶׁ֖ה עַבְדּֽוֹ.  The order seems backward, first you beleive and then you fear?  How can you fear something before you believe in it?  The Aley Shor brings from Rav Yeruchem that you can't teach אמונה to a שיכור.  Someone who doesn't fear Hashem, one has no concept at all of what it means that there is a G-d, has no capability to have אמונה.  Obviously, then אמונה isn't merely the belief in a supreme being, but is something more.
