Words can be used as weapons, therefore one should use them wisely and sparingly. On the other hand, words can be encouraging and should be abundantly used. Words bring peace, mostly when language reveals truth. One can feel peace when reading the Bible, having God's promises communicated repeatedly. After all, peace is freedom from disturbance.
Words can say so much.
It is the communication of an emotion. It can be a dream for the person hearing it, a hope that the other person will say it back, and it can also be perceived or meant as a commitment. While language has a lot of promise in communication, it has many limitations as communication. Experience cannot be captured by language. Because people are often in a story telling mood, this many times is a problem.
