God is particularly interested in what is going on within the heart of man. Specifically, He seeks for, and desires to find, TRUTH.
Man is not promised an endless supply of strength for him to store up. Rather, God promises to provide the necessary grace and strength for the present trials.
Man must spend his strength on things that matter. In doing so, we must focus our efforts upon the right things while working through and by God's power.
The land cannot continually endure the stress of producing the same crops without some time of rest for renewal. Man is no different.
