How do we know spiritual growth is important?

The necessity of spiritual growth can be seen clearly throughout the Bible, where believers are urged to transition from the immaturity of consuming 'milk' to the strength of 'meat' in the faith. Paul addresses this in 1 Corinthians 3, rebuking the Corinthian church for remaining as 'babes in Christ' and unable to handle deeper spiritual truths. This growth is not only a mark of healthy Christian life but also essential for developing a relationship with God that bears fruit and withstands challenges. Spiritual maturity equips believers to engage with the world faithfully and demonstrates the transformative power of the Gospel in their lives.
