There is power of life and death in the tongue什么意思?

原文如下：
A group of frogs were traveling through the woods,and two of them
fell into a deep pit.When the other frogs saw how deep the pit
was,they told the two frogs that they were as good as dead.The
two frogs ignored the comments and tried to jump up out of the pit
with all their might.The other frogs kept telling them to stop,
that they were as good as dead.Finally,one of the frogs took
heed to what the other frogs were saying and gave up.He fell down
and died.
The other frog continued to jump as hard as he could.Once again,
the crowd of frogs yelled at him to stop the pain and just die.He
jumped even harder and finally made it out.When he got out,the
other frogs said,"Did you not hear us?" The frog explained to
them that he was deaf.He thought they were encouraging him the
entire time.
This story teaches two lessons:
1.There is power of life and death in the tongue.An encouraging
word to someone who is down can lift them up and help them make it
through the day.
2.A destructive word to someone who is down can be what it takes
to kill them.
Be careful of what you say.Speak life to those who cross your
path.The power of words...it is sometimes hard to understand
that an encouraging word can go such a long way.Anyone can speak
words that tend to rob another of the spirit to continue in
difficult times.Special is the individual who will take the time
to encourage another.
从上下文来看,这句的意思应该是——话语中蕴含着生存和死亡的力量
如果LZ觉得合适,就多给点分吧,哈
