Words are important because we can be blessed by words or we may not.
When we say something, we can't pick up the words so we have to be careful.
The right side robber and Daniel's three friends were saved and received overflowing blessings.
It was their words that saved them. We need to know it is a lesson God gives us.
We can be hard and difficult in our life but we should thank God. Everything is God's will and he tests us for our salvation.
Thus, please don't blame God for anything. We are being tested in God's plan.

[James 1:19–25]
My dear brothers, take note of this: Everyone should be quick to listen, slow to speak and slow to become angry, for man’s anger does not bring about the righteous life that God desires. . . . Do not merely listen to the word, and so deceive yourselves. Do what it says. . . . he will be blessed in what he does.
