Why is the perfecting of the saints important?

Ephesians 4:12-13 teaches that the purpose of Christ giving gifts to the Church, such as pastors and teachers, is for the perfecting of the saints. This process of maturation is essential for building up the body of Christ, fostering unity in faith and knowledge of the Son of God. Moreover, as Paul emphasizes, the Church is called to attain to the measure of the stature of the fullness of Christ, indicating a communal growth that strengthens each believer while glorifying God. This perfecting process nurtures spiritual maturity, enabling believers to withstand false teachings and grow in love and service to one another.
