I've read a number of articles in the past few years on introverts vs. extroverts. The commonly agreed upon definition of an introvert is that an introvert is someone who gains energy by being by himself/herself. An extrovert is a person who feeds off of being around other people. People who have aspects of both introverts and extroverts are called “ambiverts.” The idea is that based on your assessment along the introvert/extrovert scale, you can more effectively recharge and work in your field.
I'd like to take just a few moments and reflect on this line of thinking from a biblical perspective. I'm not questioning that there are different personality types in the world (I tend to be more extroverted than my wife). However, I believe that God has designed every person for a rhythm of time alone and time with other people. God has called every believer to rest and recharge, and He's called every believer to reach out in love to others.
It seems fair to say that Jesus is the only perfectly balanced ambivert in the history of creation. In the gospels we see Him ministering to crowds (Mark 6:30-44; 8:1-10), and we see Him taking time alone to pray and recharge (Mark 1:35; 6:46). Was Jesus an introvert or extrovert? I think the answer is that God designed every human being who has ever lived–including God-incarnate–for a balance of pouring out to others and recharging in private.
God established a pattern of rest and work at creation. Jesus Himself engaged in personal recharge, as well as public ministry, and He established a pattern for His people to pursue both rest and work.
It's not more holy to be either an introvert or extrovert. But every Christian should spend some time in personal rest, recreation, and worship, and every Christian should be actively pursuing ministry to others. The balance will be different for each person, as those made in God's image reflect different aspects of God's creative design in different proportions. And sometimes the balance for an individual will vary based on his/her stage in life.
Pray for wisdom to know how to engage in personal worship and proactive ministry to others. Was Jesus an introvert? Sometimes… Was Jesus an extrovert? Sometimes… Remember this as you minister to others and as you seek to help those around you know how to balance life and ministry. And remember this when you are tempted to judge those with a different balance of introvert/extrovert than God gave you!
