Is it okay for a Christian to be an introvert?

TL;DR:

God made introverts just like He made extroverts. The way in which God made introverts gives them a unique way to love Him and to love others.

Introversion and extroversion are best understood as two ends of a spectrum explaining how people prefer to relate to the world. No one is completely introverted or extroverted. Neither is right or wrong; both are simply generalized descriptions of personality traits. There are positives and negatives to both introversion and extroversion. A very truncated description of an "introvert" is a person who gains energy and strength from solitude and focus on his or her inner life. Introverts tend to gravitate toward deep, one-on-one conversations rather than party small talk. They'd rather avoid crowds to spend time alone or with one or two other people. Introverts often have an active inner-thought life. Introverts also tend to express and energize themselves through solitary, and often artistic, pursuits such as painting, writing, music, and art. Introverts can glorify God and love others in the unique way God has made them.

from the old testament

Moses frequently sought solitude to meet with God on Mount Sinai (Exodus 34:28) and spent long periods in prayer and reflection.
The prophet Elijah often worked alone, relying on God’s provision in isolated settings (1 Kings 17:2–6). After confronting King Ahab and the prophets of Baal, Elijah fled into the wilderness and poured out his struggles to God. God provided food, water, and sleep for him there. Then Elijah went to Mount Horeb and lodged in a cave. There, God spoke to Him—first giving great demonstrations of power and then coming to Elijah in "a low whisper" (1 Kings 19:12–13). Elijah thought he was the only faithful prophet who remained. God met the wearied man in his solitude, instructed him, and gave him the strength to press on. God also provided Elisha (1 Kings 19:16–21).
Jeremiah often faced isolation due to the unpopular messages he brought to the people of Judah. Jeremiah grieved deeply over Israel's sins and impending judgment (Jeremiah 9:1).

from the new testament

Mary exemplified a reflective and contemplative spirit (Luke 2:19, 51).
Known for her quiet devotion, Mary of Bethany chose to sit at Jesus’ feet and listen rather than busy herself with household tasks like her sister Martha (Luke 10:39).
While Philip did not take a prominent role among the apostles, he played a quiet yet important part in the early spread of the gospel. Known for asking thoughtful questions (John 14:8) and carefully seeking understanding, Philip demonstrated a contemplative nature.
Introverted traits can be beneficial for a Christian. The practice and discipline of prayer takes stillness, quiet, and aloneness. Certainly we are to pray corporately, but Jesus also tells us to pray alone: "But when you pray, go into your room and shut the door and pray to your Father who is in secret. And your Father who sees in secret will reward you" (Matthew 6:6). Jesus also modeled this by spending time alone with God (Luke 5:16).
Being able to focus and meditate on Bible reading and study comes easier, in general, for introverts. The ability to spend time alone in sustained thought can be very beneficial in pondering the things of God. Though introverts have traits that can be applied to growing more Christlike, these same traits can also be a hindrance to sharing the gospel. Jesus tells us to go, make disciples, and teach people about Jesus (Matthew 28:19–20). This can be difficult for introverts, but it is still something we are called to do.
As Christians, we are called to spend time with others and build each other up (Hebrews 10:24–25). Introverts are not exempt from the need of fellowship and cannot use their personality trait as an excuse to disobey God's Word. However, it is also important to recognize that fellowship does not require a large group or a lot of noise or activity.
God has made us each unique and given His children spiritual gifts for the mutual edification of the church (Psalm 139; 1 Corinthians 12). Introvert or extrovert, we each struggle with sin. There are strengths and pitfalls to any personality type.
No matter our particular tendencies, God is able to equip us to do what He calls us to do (2 Peter 1:3). We simply seek Him, submit to Him, and allow Him to transform us into people who more closely resemble Christ (Romans 8:29; Philippians 1:6; 2:12–13). When our personality tendency helps us in our walk with Christ, we give Him praise for it and make the most of the gifts He has given. When our personality tendency gets in the way of obedience to Christ, we ask for His power to help us live beyond ourselves.

implications for today

Introverts, like everyone, should watch their motivations for how they act. Some introverts can spend time alone to avoid people due to fear or insecurity. Introverts are more apt to struggle with self-image and a critical spirit. God tells us to view others with respect and gain our identity from Him (Philippians 2:3–4; Ephesians 2:10). We cannot use a personality trait as an excuse to disbelieve God's Word about who we are in Christ and how we should live as a result. Rather, introverts can leverage their strengths to draw closer to God and find security in Him. Security in our identity in Christ comes from spending time with God. Loving others comes from first receiving God's love for us (1 John 4:7–12).
