I am including this Psalm because it is so meaningful to me personally. We should strive to be a Psalm 112 man or woman. Particularly note verses 7 and 8: the revived heart rests soley on God and is not moved by the circumstances of this world.
 

1. Praise ye the LORD. Blessed [is] the man [that] feareth the LORD, [that] delighteth greatly in his commandments.
2. His seed shall be mighty upon earth: the generation of the upright shall be blessed.
3. Wealth and riches [shall be] in his house: and his righteousness endureth for ever.
4. Unto the upright there ariseth light in the darkness: [he is] gracious, and full of compassion, and righteous.
5. A good man sheweth favour, and lendeth: he will guide his affairs with discretion.
6. Surely he shall not be moved for ever: the righteous shall be in everlasting remembrance.
7. He shall not be afraid of evil tidings: his heart is fixed, trusting in the LORD.
8. His heart [is] established, he shall not be afraid, until he see [his desire] upon his enemies.
9. He hath dispersed, he hath given to the poor; his righteousness endureth for ever; his horn shall be exalted with honour.
10. The wicked shall see [it], and be grieved; he shall gnash with his teeth, and melt away: the desire of the wicked shall perish.
