He was bruised as every son is chastened for corrective purposes only. In Heb.11, the suffering of the OT faithful is described. Then he says to the church,
The Son of God is not chastened for corrective purposes only, because the corrective purpose is to heal us of our stripes.Ye have not yet resisted unto blood, striving against sin. Heb.12:4
He's speaking of how our Savior strove against the human desire to judge those who "contradicted" him (vs.3) enduring shameful treatment (vs.2).
Gods' correcting his only begotten Son? Why?
Isaiah 53:5 But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed.
But to take patiently, suffering when you do well, that is acceptable with God.
We are called even to that, Christ suffered for us, leaving us an example, to follow His steps, who did no sin, no guile in His mouth, when reviled, reviled not again, when He suffered He threatened not, but the Son committed Himself unto the Father that judges righteously. Christ bore our sins in His own body on the tree, so that we being dead to sins, live unto righteousness, as by the Sons stripes, we were healed. ( of unrighteousness.)
1 Peter 2:20 For what glory is it, if, when ye be buffeted for your faults, ye shall take it patiently? but if, when ye do well, and suffer for it, ye take it patiently, this is acceptable with God.
21 For even hereunto were ye called: because Christ also suffered for us, leaving us an example, that ye should follow his steps:
22 Who did no sin, neither was guile found in his mouth:
23 Who, when he was reviled, reviled not again; when he suffered, he threatened not; but committed himself to him that judgeth righteously:
24 Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed.
25 For ye were as sheep going astray; but are now returned unto the Shepherd and Bishop of your souls.
The Father saw that travail of His Son, and that satisfied ( pleased) Him, because His righteous servant ( the Son who left us an example of suffering patiently) justified many, as He bore our sins. ( He did what was appointed to Him.)
Isaiah 53:11 He shall see of the travail of his soul, and shall be satisfied: by his knowledge shall my righteous servant justify many; for he shall bear their iniquities.
12 Therefore will I divide him a portion with the great, and he shall divide the spoil with the strong; because he hath poured out his soul unto death: and he was numbered with the transgressors; and he bare the sin of many, and made intercession for the transgressors.
The answer is given in verse 3, and to look to Jesus who directs our faith in righteousness, is to also not be wearied in our mind nor faint, because the chastisement OF OUR PEACE, was upon Him.
Isaiah 53:5 But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed.
Hebrews 12:2 Looking unto Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God.
3 For consider him that endured such contradiction of sinners against himself, lest ye be wearied and faint in your minds.
Our chastening is to yield the peaceable fruit of righteousness, and looking to Jesus patiently enduring, it lifts up the hands which hang down, and the feeble knees, and it makes straight paths for our feet, so the lame is not turned out of the way, but it is healed. ( by His stripes we re healed.)
Hebrews 12:11 Now no chastening for the present seemeth to be joyous, but grievous: nevertheless afterward it yieldeth the peaceable fruit of righteousness unto them which are exercised thereby.
12 Wherefore lift up the hands which hang down, and the feeble knees;
13 And make straight paths for your feet, lest that which is lame be turned out of the way; but let it rather be healed.
