Developing virtues like goodness, knowledge, self-control, perseverance, godliness, mutual affection, and love is essential for a fruitful Christian life. These qualities, when nurtured and expanded upon, prevent believers from becoming stagnant or ineffective in their spiritual walk. They serve as a foundation for a deeper understanding and connection with Jesus Christ, ensuring that one's faith is not just a passive belief but an active, living expression of Christ's teachings.
The emphasis on 'increasing measure' suggests that spiritual growth is a continual process. As believers strive to embody these virtues more fully, they become more effective in their witness and service, reflecting Christ's love and wisdom to the world. This growth not only benefits the individual but also enriches the community of faith, as each person's development contributes to the collective strength and vitality of the church. By focusing on these qualities, Christians can ensure that their knowledge of Christ is not just theoretical but practical and transformative.
