The tongue also is a fire, a world of evil among the parts of the body. It corrupts the whole body, sets the whole course of one’s life on fire, and is itself set on fire by hell.

James 3

The tongue also is a fire, a world of evil among the parts of the body. It corrupts the whole body, sets the whole course of one’s life on fire, and is itself set on fire by hell. v6

Indeed, words can be fraught with harm and hurt so we must be careful - as much as anybody I know this as I have been on the delivering end of harmful and hurtful words.

On the other hand:

All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the servant of God may be thoroughly equipped for every good work. 

2 Timothy 3:16-17

...

For no word from God will ever fail. Luke 1:37 

My Prayer: Lord Jesus, You are a great God and Your Word is perfect, never harmful or hurtful - always for good, and it will never fail!  How awesome a God are You!  I am blessed beyond description to have such a God - a God who chose me!  Thank You Jesus.  Thank You also for Your patience, mercy, compassion, etc. Please forgive me for my neglect of You and for my focus on my own comfort instead.  Help me overcome and turn from such sin and turn towards You instead.  Help me love You with all of my heart, soul, mind, and strength.  Help me love others as You do.  Help me grow in my faith.  Help me use my tongue wisely.  Give me strength.  Give Lisa comfort, strength, and freedom from pain.  Please heal and cure Lisa of this cancer.  Help this surgery go successfully!  Help me lead and serve Lisa, Zach, and Dustin.  Help me understand, be obedient to, and apply Your message for me today and every day.
