Hebrews 5: 5 So also Christ glorified not himself to be made an high priest; but he that said unto him, Thou art my Son, to day have I begotten thee.
6 As he saith also in another place, Thou art a priest for ever after the order of Melchisedec.
7 Who in the days of his flesh, when he had offered up prayers and supplications with strong crying and tears unto him that was able to save him from death, and was heard in that he feared;
8 Though he were a Son, yet learned he obedience by the things which he suffered;
9 And being made perfect, he became the author of eternal salvation unto all them that obey him;
10 Called of God an high priest after the order of Melchisedec.
When Christ left His Father’s side to come to this earth to suffer, to be tempted and to die so that He could be the high priest who offered the final sacrifice for sin–one of His greatest pains was the horror of the separation from the glorious, brilliant presence of the Father. We sometimes take too lightly the sacrifice it took for Christ to become human. He continuously went before the Father in prayer each morning (an example well set for us)–He cried out to the Father from the Garden of Gethsemane because in His humanity He suffered the agony that a human would suffer. Though He had the power to call legends of angels at any time, He chose to in humble obedience endure the mockery, the beatings, and the cross to offer salvation to the very ones who rejected Him. Christ had never been disobedient; yet, where it says he learned obedience it is referring to the fact that in His humanity His obedience was put to the truest test and in that He remained obedient. Though He was always perfect, His Glory and perfection were magnified by His enduring such temptation without sin.
