What does God see in Israel that so affronts Him that He has to swear "by His holiness"? Israel had every opportunity that the Gentiles did not have: His calling, His promises, His Word, His laws. He gave the Israelites these gifts to help them develop into His sons and daughters, but God sees them as diametrically opposite of Himself. Should not God expect to see some of His characteristics in His sons?
John Ritenbaugh observes that ancient Israel had at the core of its religion (as well as its dominant cultural norm) an obsession to serve or please the self at the expense of justice and truth and the best interests of the socially disadvantaged. Because of Israel's excessive self-seeking and self-serving pride, God threatens to remove His protection, allowing its people to go into captivity. Pride (the catalyst for Laodiceanism) causes people to reject God and to follow idolatrous ways. Israel's leaders should 1) never be content with the way things are, 2) never let care and concern for self take priority over the welfare of others, 3) covet peace with God, but only on His terms, 4) choose things that are more excellent, and 5) embrace morality.
John Ritenbaugh, expanding on God's swearing by His Holiness, adds that when God looks upon people who call themselves by His name, He expects to see certain family characteristics- exemplified by holiness, purity, and morality. Amos indicated that God could not identify these characteristics in people appropriating His name. God's called out ones are obligated to avoid defilement from any source whatsoever, taking special care not to mix God's truth with worldly tradition and rank paganism, forming a syncretistic religion. Amos, using the unflattering image of cows of Bashan, censures the women of Israel (normally the safeguard for the family morality) for abandoning morality, living exclusively for pleasure, materialism, and self-centeredness (often at the expense of the poor and needy), while practicing devoutly a form of syncretistic religion. God, through His prophets, warns that God (with a motive of love) will chasten His people with increasing severity until they repent and begin to reflect His characteristics.
John Ritenbaugh reiterates that the "favorite-son status" of Israel was conditional, based upon accepting the terms of their covenant with God. Unfortunately, both ancient and modern Israel have placed their trust in wealth or material things rather than God. God's anger has been aroused as a result of Israel's physical and spiritual defilement—refusing to become sanctified, separate from the ways of the world. God's holiness sets Him apart from everything else, and like Him, His people must become totally different from the world. Instead, our defilement, stemming from our desire to please the self at the expense of others, separates us from Him! The root of sin or immorality lies in man's desire to live his life in self-centered independence from God. We must enlist God's Spirit to kill our self-centered ego, yielding to God's transforming power.
John Ritenbaugh focuses upon the superiority of Christ and the Melchizedek priesthood, pointing out that in every way it is superior to the Aaronic priesthood because Christ tenure is eternal rather than temporal, guaranteeing both continuity and quality. Hebrews 7 is the only portion of scripture that carefully examines Christ's credentials as High Priest, giving us concrete hope of our salvation. His blameless and undefiled life made Him an appropriate guarantor or co-signer covering our imperfections. After establishing the need for a change of the priesthood, Paul describes the details as to how the new priesthood will administer the New Covenant, amplifying and bringing into stark reality what had been only seen in shadowy outline in the Old Covenant. The New Covenant is established on better promises, not law changes.
John Ritenbaugh emphasizes the importance of exercising faith and hope, patiently plodding along day-by-day toward our spiritual goal. Many of the pillars of faith had to wait many years (Abraham, for example, waited over 25 years before he saw the beginning of the fulfillment of God's promise) for the fruition of their faith's target. With godly hope, we need to envision the possibility of successful accomplishment of God's purpose for us, realizing that God has bound that promise with an oath and that Jesus Christ (having empathy for us) intercedes for us as High Priest. Melchizedek, a prototype as well as equivalent of Christ, establishes the validity and dignity of Christ as High Priest. The divine appointment of Jesus as our High Priest precedes our divine calling, more important than genealogy or external physical characteristics.
