Why is humility important for Christians in their growth?

Biblically, humility is often cited as a sure mark of spiritual growth. The Apostle Paul exemplifies this in his writings, identifying himself progressively as 'the least of the apostles' and 'the chief of sinners' (1 Timothy 1:15). Such humility reflects an accurate recognition of our shortcomings and dependence on God's grace, fostering a disposition of teachability, repentance, and faithfulness in growth. As Christians grow, they develop a heart that is more aware of their need for God's mercy, leading them to a deeper, more fruitful walk with Him.
