Put no confidence on mundane things

Jer.17.5 - This is what the LORD says: "Cursed is the one who trusts in man, who depends on flesh for his strength and whose heart turns away from the LORD. Jer.17.6 - He will be like a bush in the wastelands; he will not see prosperity when it comes. He will dwell in the parched places of the desert, in a salt land where no one lives. Jer.17.7 - "But blessed is the man who trusts in the LORD, whose confidence is in him. Jer.17.8 - He will be like a tree planted by the water that sends out its roots by the stream. It does not fear when heat comes; its leaves are always green. It has no worries in a year of drought and never fails to bear fruit." Jer.17.9 - The heart is deceitful above all things and beyond cure. Who can understand it? Jer.17.10 - "I the LORD search the heart and examine the mind, to reward a man according to his conduct, according to what his deeds deserve."
