Why is growing in grace essential for Christians?

2 Peter 3:18 urges believers to grow in grace and in the knowledge of our Lord Jesus Christ. Spiritual growth is essential because it reflects a deeper understanding and appreciation of God's unmerited favor towards us. As Christians mature in grace, they become more equipped to withstand trials and encouraged to live out their faith actively. This growth fosters a stronger relationship with Christ and enables believers to share the good news of the gospel faithfully. Moreover, it counters the tendency to forget God's works and promises, ensuring that believers remain steadfast in their faith.
