SPIRITUAL ADOPTION AND HEIRS OF GOD
THE OLD AND THE NEW COVENANTSGalatians 4. 1-10
In these verses Paul compares Israel to a "child" that does not yet inherit the Estate of his Father, but the "child" is under guardians and managers, means under the Rules and Regulations of the Law of Moses. During the time of the Law of Moses Israel is submitted to "elemental things" (or "elemental spirits" or rudiments. NRSV).
It may mean the basic and simple Laws and Regulations of the Ritual Law and Behavioral Law of GOD that are given to Moses as the start of educational process of Israel. The elementary Ritual Laws of Moses was the first step of educational process, because Israelites at that time were are not Spiritually ready to learn much more higher standards of the Spiritual Laws of Moses.
In verse 4 position and environment of Israel completely changed with the coming of Jesus Christ the Son of GOD, Who was born of physical woman, and born under the Law of Moses under which Israel obligated to obey and fulfill it as their Covenant with GOD. Despite the fact that Jesus brought the Spiritual Commandments of the Law of Moses to Israel as their New Covenant to replace the Covenant of Rituals, Jesus Himself continued followed the Ritualistic Law of Moses as it was prescribed in the Law, in order to show to Israel that the both Laws can be obeyed and fulfilled and nothing is impossible in it.
Also, Jesus proved to all who doubt Him about His genealogy that He is the real Jew, and not just an ordinary Jews but from the tribe of Judah, descendant of David, royal Descendant.
~ 4. Genealogy of Christ: Luke 3.23-28, Matthew 1.1-17.
Verse 5 specifies one very important aspect of Jesus coming, He came to "Redeem those who were under the Law" under the Ritualistic Law of Moses, because of numerous violations of it by the leaders and by the people. Redemption of Christ came in form of Spiritual Commandments of the Law of Moses-the Gospel, to adapt Israel and the world by the Spiritual adoption of the Spiritual Law. To have for GOD not physical sons and daughters, but the Spiritual sons and daughters ready to enter His Spiritual Kingdom.
This signifies a new era in Spiritual worship and service of GOD.
John 4.23-24
23. "But an hour is coming and now is, when the true worshipers shall worship the Father in spirit and truth, such people the Father seeks to be His worshipers.
24. GOD is Spirit, and those who worship Him must worship in spirit and truth."
Romans 12.1
1. "I urge you therefore brethren, by the mercies of GOD to present your bodies a living and holy sacrifice acceptable to GOD, which is your spiritual service of worship."
To Philippians 3.3
3. "It is we who are the true circumcision, who worship in the Spirit of GOD, and boast in Christ Jesus, and have no confidence in the flesh,"
Verse 6 goes even further declaring Spiritual worshipers of GOD as "sons," to whom "GOD has sent forth the Spirit of His Son into our hearts." This is very similar to a statements made in other places of the Bible.
~ Writing on the hearts: (2Chronicles 30.12) (Psalm 40.7-8) (Proverbs 7.3) (Isaiah 44.3) (Jeremiah 24.7, 30.22, 31.33, 32.38.40) (Ezekiel 36.26-27, 39.29) (Zephaniah 3.9) (Hebrews 10.16-17) (2Corinthians 3.3).
Verses 7-8 describes the change from submission "slavery" to the Ritualistic Law and the world in general, to a Spiritual "son" of GOD and Spiritual "heir" of GOD'S Kingdom "through GOD," precisely through Jesus Christ.
In verses 9-10 Paul wrote to Philippians with rebuke, because the course of their church turned back to "elementary things" as Paul describes it in verses 3 and 9.
The verse 10 perhaps describes some of these "elementary things" with a word "observe" and in some Bibles with the words "observe special." This may indicate some kind pagan worship of heavenly bodies, or some special occasions or events related to sorcery or some kind magic forbidden by GOD.
In general description the result of such transition from "elementary things" of the Ritualistic Law of Moses to mush higher level of Spiritual Laws of Moses reveal itself in magnificent transformation like metamorphosis, from ordinary to extraordinary, from mortal physical flesh (23.29) to a Spiritual everlasting being, inside of whom the Spirit the Christ is formed.
Following verses 21-31, they describe the difference between Sarai and Hagar and the difference between Ishmael and Isaac. Paul emphasize difference between slave and free. Paul related Hagar to the ordinary earthly woman who produces ordinary earthly child Ishmael, from whom will come earthly ordinary descendants.
On the other hand, Paul portrait Sarai as not ordinary earthly but extraordinary woman, to whom special Spiritual Promises of GOD concerning her son Isaac and his descendants was made to her. (Genesis 17.1-22).
While Hagar and Ishmael also received from GOD and their revelation concerning their future, but it is very different from Sarai and Isaac (Genesis 16.9-12, 17.20, 25.12-18).
Verse 29 also gives us some clue concerning One Special Descendant of Isaac. In the second part of the verse Paul stated that Ishmael persecuted Isaac, means the descendants of Ishmael will persecute descendants of Isaac, and even today are witnesses of this incredible prophecy of persecution.
Because from Isaac's descendants will come Jesus Christ who will be persecuted and eventually Crucified by Gentiles, Paul made here excellent comparison with Isaac, the genealogical forefather of Christ, that Isaac "was born according to the Spirit," the Spirit of Christ. This entire verse 26 reveal the everlasting straggle between descendants of Ishmael who represent the ungodly evil of the world that constantly persecute descendants of Isaac who represent in this world as Jews, the descendants of Jesus Christ. In other words, those who persecute Jews and Judeo-Christians, persecute also Jesus Christ.
In verse 26 Paul now relate Sarai as our spiritual mother, in the same way Paul often reminded us that all who have Faith of Abraham are his Spiritual sons. So, in this sense we have not only Spiritual father but also and Spiritual mother, we have Spiritual Family which is much more important and higher than our ordinary earthly family, because Spiritual Family is the Family of GOD that never feud, never argue, never betray, never disappoint, and never separates, not like the ordinary families on Earth.
Paul presented Old and New Covenants as they both related to the descendants of Abraham who in their Faith, Fear, and Obedience worship and serve the Lord GOD. They are all Spiritual sons of Abraham.
