Hebrews 5:1-6 In the Old Testament, the High Priest had to offer sacrifices for his own sins, and because of this, he could deal gently with those that come to him for the purpose of performing sacrifices for them. Christ in the same was appointed High Priest by His Father after the order of Melchizedek.
Notes: No angel with supernatural power could serve as high priest. That is why Jesus was made a little lower than the angels in order to be appointed to this office. Melchizedek was the king of Salem (later called Jerusalem) and priest of the Most High God in the time of Abraham. He was also a king-priest, just as Jesus was. There is no record of his father or mother or any of his ancestors--no beginning or end to his life. He remains a priest forever, resembling the Son of God.
Hebrews 5:7-10 In the garden of Gethsemane, Jesus offered up prayers to His Father to save him from the death he was appointment. Jesus learned obedience through what he suffered and was made perfect, becoming the source of our salvation.
Notes: Jesus learned obedience for the same reasons he bore temptation: to confirm his humanity and experience its sufferings to the fullest. Christ’s obedience was also necessary so that he could fulfill all righteousness and thus prove to be the perfect sacrifice to take the place of sinners. He was the perfectly righteous One, whose righteousness would be imputed to sinners.
Hebrews 5:11-14 The writer of Hebrews goes on to say that he wished he could say in more depth about the complex relationship between the Father and the Son, but said that his readers were dull of hearing, still babies in Christ, although they should by now be teachers themselves. Those who have matured in the faith have the powers of discernment trained by constant practice to distinguish the difference between good and evil.
