What does the Bible say about humility in serving God?

Humility in serving God is fundamental to the Christian faith, as encapsulated in John 3:30, where John the Baptist states, 'He must increase, but I must decrease.' This reflects the attitude a believer should have, understanding that service to Christ, regardless of its perceived significance, is a privilege and an honor. John exemplified this by considering himself unworthy to unlatch the shoes of Jesus, a task seen as menial yet he revered the opportunity to serve the Lord in any capacity.
