"... He then called the crowd together and said, 'Listen, and take this to heart. It's not what you swallow that pollutes your life, but what you vomit up ... Don't you know that anything that is swallowed works its way through the intestines and is finally defecated? But what comes out of the mouth gets its start in the heart. It's from the heart that we vomit up evil arguments, murders, adulteries, fornications, thefts, lies, and cussing. That's what pollutes. Eating or not eating certain foods, washing or not washing your hands—that's neither here nor there." (Matthew 15:16-20, The Message)
I ran across this on the Web: "The power of a keystroke."
Not too long ago, keystrokes were primarily generated by large printing presses of companies that published books and magazines as well as secretaries who typed for their bosses.
Newer technologies like the personal computer, the Internet, texting on phones, etc, have changed all that.
More people are keyboarding and with a wider audience.
However, the pollutted condition of the human heart is not new.( Jeremiah 17:9; Romans 5:12)
We're just seeing more of it because of the new technology.
But, the power is not in the keystroke.
The power is in the heart.
The keystroke is a by-product of the heart.
A person types what's in his heart.
"Since, then, you have been raised with Christ, set your hearts on things above, where Christ is seated at the right hand of God. Set your minds on things above, not on earthly things. For you died, and your life is now hidden with Christ in God." (Colossians 3:1-3, NIV)
