As an introvert you may find you have a greater appreciation of subtlety and understatement — talents that, when harnessed, can become great strengths. Taking longer to answer questions is not a personality flaw, but means that you’re making more mental connections and your answers are likely to contain more substance. Extroverts would have to make an effort to think as deeply as you do naturally.
Your self-sufficiency also can be an advantage, as you don’t habitually judge yourself in terms of how others rate you. On the contrary, you are able to focus clearly on your day’s achievements.
Without the pressing need to be sociable or gain attention and approval, you can spend time on relationships and close friendships, which are often more profound than those shared by extroverts.
I have come to appreciate my gift of being able to pick up subtle things about people. Maybe I am an exception to the rule of introverts, but I do enjoy being around people. I just like listening. In group gatherings, I don't mind not being in the middle of the conversation as long as I can observe.
So if I am a part of the body of Christ, I guess I am the ear. This whole time I have been frustrated that my ear cannot talk. Now I am ready for God to use my ability to observe to serve others.
