Adam Clarke's Commentary on the Bible

Verse 4 (Proverbs 13:4)

The soul of the sluggard desireth and hath nothing - We often hear many religious people expressing a desire to have more of the Divine life, and yet never get forward in it. How is this? The reason is, they desire, but do not stir themselves up to lay hold upon the Lord. They are always learning, but never able to come to the knowledge of the truth. They seek to enter in at the strait gate, but are not able, because they do not strive.
