'Suffering' 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].

Because He Himself [in His humanity] has suffered in being tempted, He is able to help and provide immediate assistance to those who are being tempted and exposed to suffering.
