Poverty and failure have roots and laziness is an obvious one
One of the reasons for spiritual coldness and lukewarmness is negligence and laziness.
Marital failure, financial poverty, failure in ministry and many other forms of poverty can all be traced back to the same root of negligence or dealing with a slack hand.
“He becometh poor that dealeth with a slack hand: but the hand of the diligent maketh rich” (Proverbs 10:4)
