'Maturity' in the Bible

For it was fitting for God [that is, an act worthy of His divine nature] that He, for whose sake are all things, and through whom are all things, in bringing many sons to glory, should make the author and founder of their salvation perfect through suffering [bringing to maturity the human experience necessary for Him to be perfectly equipped for His office as High Priest].

Therefore let us get past the elementary stage in the teachings about the Christ, advancing on to maturity and perfection and spiritual completeness, [doing this] without laying again a foundation of repentance from dead works and of faith toward God,

By faith Moses, when he had grown up, refused to be called the son of Pharaoh’s daughter,

[looking away from all that will distract us and] focusing our eyes on Jesus, who is the Author and Perfecter of faith [the first incentive for our belief and the One who brings our faith to maturity], who for the joy [of accomplishing the goal] set before Him endured the cross, disregarding the shame, and sat down at the right hand of the throne of God [revealing His deity, His authority, and the completion of His work].
