Why is Christian maturity important for believers?

Paul addresses this in Philippians 3:15, encouraging those who are spiritually mature to be of the same mind. Maturity in the Christian faith involves recognizing that we have not arrived and that we must continually seek to know Christ more deeply. Understanding that we are still maturing allows believers to guard against errors such as the belief in sinless perfection. True spiritual growth involves continually realizing our need for Christ and His righteousness rather than placing confidence in ourselves. Such maturity fosters a humble acknowledgment of our progress and reliance on God’s teaching as He guides us into all truth.
