For every careless word men may speak, they will give account of it in the day of judgment. For by your words you will be justified, and by your words you will be condemned (Matthew 12:36-37).
It’s been estimated that the average person talks enough each day to fill a book of 50-60 pages – a year’s equivalent of 100 books of 200 pages each! What many people don’t realize is that they will one day be judged by God for the very words they’ve spoken during their lifetime.
In Matthew 12:33-37, Jesus taught that fruit reveals the nature of a tree. A sick tree produces poor fruit; but a healthy tree produces abundant fruit. Then He applied it to the human heart.
What the heart dwells upon is expressed in words. Our words are a gauge of our heart; our words either justify or condemn us. Jesus said that each of us will have to give an account for every careless (useless, barren, vulgar, blasphemous) word ever spoken.
The Christian’s speech reflects God’s transforming work (Ephesians 4:29-32; 5:18-21); but the unbeliever’s worthless words will condemn him in the day of judgment (Luke 19:22).
