'Growth' in the Bible

One who speaks in a tongue edifies himself; but one who prophesies edifies the church [promotes growth in spiritual wisdom, devotion, holiness, and joy].

and not holding fast to the head [of the body, Jesus Christ], from whom the entire body, supplied and knit together by its joints and ligaments, grows with the growth [that can come only] from God.

Epaphras, who is one of you and a bond-servant of Christ Jesus, sends you greetings. [He is] always striving for you in his prayers, praying with genuine concern, [pleading] that you may [as people of character and courage] stand firm, [spiritually mature] and fully assured in all the will of God.
