I don't think we take introductions serious. Introductions and knowing someone's name is the starting place for building relationships and getting to know people better. I don't think someone is really interested in getting to know me as a person and building a relationship if they can't remember my name. I visit a lot of churches and greet a lot of people. Many in the church come up quickly, shake my hand, and say with an automatic response, "It's good to meet you." I respond with, "We haven't met yet. My name is Charles, what's your name?" It throws people off from the quick greeting they are accustomed to. There is a big difference between a quick "glad to meet you" versus actually meeting someone by extending a pleasant acknowledgement and name exchange.
For those who want to know God better, there is hardly a richer approach than to explore the names, the titles, and the metaphors through which God has presented Himself to us in His Word. These names unveil the essence of who God is. These names describe His qualities and character, and they reveal His work in our lives.
For most of human history, names given to deity by pagans only served to distance human beings from the one true God. Man called God names that for the most part reflected their superstitions and religious ignorance. However God would not have us remain ignorant concerning His name and His character. God our Father stepped in to reveal Himself to His Old Testament people.
Why is it important for us to know God by His name and His character? If we know who God is in His power and character than as a believer I know that He can do what He says He can do. Example! I don't take my car to a Mexican restaurant to have repairs. I go to a place that has the name, reputation, and character of having the ability to accomplish the task I need. In reverse, I don't go to a car repair garage to eat Mexican food. I go to a restaurant that specializes in Mexican food. How do I know these places? By their name. So it is with our heavenly Father. As I know His different names I fully understand His character.
