Heb 7:10  For he was yet in the loins of his father, when Melchisedec met him. 

Heb 7:11  If therefore perfection were by the Levitical priesthood, (for under it the people received the law,) what further need was there that another priest should rise after the order of Melchisedec, and not be called after the order of Aaron?

Browsing through commentaries on 'order' and/or 'Melchizedek(c).  This from Gill on Hebrews 7:11:

"what further need was there that another priest should arise after the order of Melchisedec, and not be called after the order of Aaron? that there was another priest promised and expected, and that he should arise after the order of Melchizedek, and who was to make his soul an offering for sin, is certain, Ezr_2:63 and such an one is risen, even Jesus of Nazareth; and yet there would have been no need of him, and especially that he should be of a different order from Aaron's, had there been perfection by the Levitical priesthood."

I was pondering upon the order of Aaron and how there is difference between the 'priests'.  One was a temporary, while the other eternal.  One demanded obedience by strict law, while the other (because of the inward change) woos us to love the Lord with all our spirit, soul and body.  To give unto Him who has given so liberally to us.  Not demanding devotion, time, sacrifice.  Waiting ever so patiently as we are transformed into His image to give a better representation of Him.

O' Father, how grievous are we in Your sight?  How oft do we love that which gives pleasure to our flesh, despising deep fellowship with You and Your Word.  Halting in our duty to You.  O' Lord, create a passion and desire to know You more intimately, to long for fellowship with You in Your Word.
