Another interpretation: As long as you dispute with me, the Omnipresent performs for you wonders and mighty acts, and My Name is magnified.
Your Quarrels Give the Lord Occasion for Wonders
Yalkut Shimoni on Torah 261:16
דָּבָר אַחֵר, כָּל זְמַן שֶׁאַתֶּם מִדַּיְּנִים עִמִּי, הַמָּקוֹם עוֹשֶה לָכֶם נִסִּים וּגְבוּרוֹת וּשְׁמִי מִתְגַּדֵּל.
