Musar do Ozeasza 11:10

But for a man in whom this longing does not burn as it should, a good advice for him is to act with zeal by force of will in order that this will bring an inner awakening of this longing in his inner nature. For the external movement rouses the inner ones and certainly the external movement is more in his power than the inner ones. Thus, if he exercises what is in his power to do, this will lead him to also attain what is not in his power. For an inner joy will awaken within him and a desire and longing through the power of acting fiery, externally, by the force of will. This is what the prophet said- "let us know, let us run to know the L-rd" (Hoshea 6:3) and "After G-d they will go, who shall roar like a lion"(Hoshea 11:10).

This looking into will cause him to not grow lazy or lax in His service. For since it is impossible for him to repay G-d, blessed be His Name, for His goodness, he will feel that at least he can thank His Name and fulfill His commandments.
