Communication is the primary means we have for connecting with others, for creating and maintaining relationships. We have at our disposal complex forms of language (which includes both spoken and written), as well as the language of gestures, facial and other physical expressions, non-verbal vocal sounds, and as our choices in clothes, cars, art, furnishings and many other things that reflect our unique personalities and communicate who we are.
It is helpful to view communication as THE tool for building relationships. The Bible is a record of God relating with individuals and societies and them relating with Him. It is often called God’s love letter because it is a primary tool we have for learning what He is like and how He relates to us.
