Satan speaks his “thoughts”. His thoughts enters the mind where the seed is planted, travels to the heart where the seed takes root, then comes out of the mouth giving birth to destruction.
How do we counter act these effects?
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.
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.
7 “But blessed is the man who trusts in the LORD,
whose confidence is in him.
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.” Jeremiah 17:5-8
