Proverbs 10:4 KJV — He becometh poor that dealeth with a slack hand: but the hand of the diligent maketh rich.
The widow with the judge. The servants with the talents. Jesus preaching, teaching and demonstrating the Kingdom, travelling to all the villages and sleeping on the boat rides. Saul being let down by a basket in Damascus. Saul/Paul working as a tent maker to pay his way in preaching the Gospel. Paul (again) being beaten, left for dead, shipwrecked, persecuted, imprisoned, flogged, abandoned but still preaching the Gospel, writing letters to the various Churches.
Diligence is a new testament quality.
Be diligent.
