What is the significance of being 'diligent' in one's faith?

Being 'diligent' in faith is significant because it denotes an earnest and sincere commitment to seeking God's glory above all else. According to Proverbs 21:5, the thoughts of the diligent 'tend only to plenteousness,' implying that genuine pursuit of God results in spiritual abundance. This diligence arises from the Holy Spirit's transformative work within a believer, enabling them to view their righteousness as a gift from Christ rather than a product of their own efforts. Such a heart is marked by humility and a desire to honor God, setting a foundation for true spiritual growth and service.
