According to Ephesians 4, it is God’s will that the church grow and become more mature. That the body of Christ, with all it’s members
“attain to the the unity of faith and the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ, so that we may no longer be children, tossed to and fro by the waves and carried about by every wind of doctrine, by human cunning, by craftiness in deceitful schemes.”
And many other scriptures make this point. For example:
“Yet among the mature we do impart wisdom, although it is not a wisdom of this age or of the rulers of this age” ( 1 Corinthians 2:6).
“Whoever abides in the teaching has both the Father and the Son” (2 John 9).
“Brothers, do not be children in your thinking. Be infants in evil, but in your thinking be mature” (1 Corinthians 14:20).
“…if you abide in my word, you are truly my disciples” (John 8:31).
