Every kind of beast and bird, reptile and sea animal, can be tamed and has been tamed by human genius. But the human tongue can be tamed by no man. It is a restless evil, full of deadly poison. With it we bless the Lord and Father, and with it we curse men who were made in God’s likeness! Out of the same mouth come forth blessing and cursing. These things, my brethren, ought not be so. James 3:7-10 AMPC

The Bible says we have the power of life and death in our tongue (various including Proverbs 18:21). We can use our words to change the course of lives. By one timely word. Speak carefully.
