What I'm going to tell you is UNCOMMON KNOWLEDGE,.....so don't think you can check with someone and they will agree, understand, or WANT to agree/understand, just use your common sense to believe whatever makes sense to you.
In O.T. times, the Jews did not know that God had a son (their promised Messiah hadn't come yet and they also did not know it would be His SON). For that reason, the Jews only worshipped "Jehovah" (they also could not have ETERNAL "purification"/salvation for their SOULS).
The Jews were able to obtain only TEMPORARY "purification" for their violations of MOSAIC LAW (which was a combination of what Moses brought down from the mountain PLUS all the rules/ordinances that Moses 'dreamed up'/invented) by performing rituals of animal sacrifices ("the blood of bulls and goats" was most common) and offerings to Jehovah God, but these rituals had to be repeated every year on the day of atonement.
"by abolishing in his flesh the law of commandments and ordinances".
Now, the law we are to be judged under is the LIBERTY "law" (not earthly logical for LIBERTY to be LAW, is it?...it is GODLY LOGICAL).
James 1:25 "PERFECT law".
"So speak and so act AS THOSE to be judged under the LAW OF LIBERTY".
Now (for us), JESUS is the FINAL and everlasting/ETERNAL sin sacrifice (now we worship 'GOD ETERNAL', same God, different dispensation/covenant) and His "eternal Spirit" (same spirit, different dispensation/covenant).
"ETERNAL spirit......purify your conscience".
God sent Jesus in "the fulness of time" (the completion/end of "time"). Jesus ended the age of time and started the age of ETERNITY (now God's purification is ETERNAL, not TEMPORARY). Blue Letter Bible - Search Results for RSV
God always had a "Spirit" ("Spirit of Holiness", Holy Spirit).
Jesus is now the COMPLETION/ENTIRETY of God,....and so, you will see that 2 John 1:9 says that we now have "BOTH the Father and the SON" (God's Spirit is now all inclusive/integral and needs no separate mention).
"does not abide in the doctrine of Christ does not have God; he who abides in the doctrine has both the Father and the Son".
That's right, our worship is of 'GOD ETERNAL'. It is likely that no one understands this (or ever did), so if you expect someone to be able to agree with what I've written, you will not only be disappointed, but you will hear a lot of "Bu...BU..but, I du know, it sounds crazy, it must mean something else" and "Forget about nonsense, just keep "FOLLOWING" like a good puppet/soldier and bring us your money".
There are many things that were never understood by believers and scholars. TRUTH is unnecessary for the modern day moneychangers (Judaizers), in fact, it is counterproductive to them because they just want us to be OBEDIENT TO 'THEM' and have us keep bringing them our money (we are not good stewarts unless all our money goes to our family). Incident at Antioch - Wikipedia, the free encyclopedia
"and in Antioch, the disciples were first called Christians".
Seventeen years after the crucifixion, the Jews that came to Christ decided at the "Incident at Antioch" to no longer be MEMBERS OF "THE WAY" because they still wanted to follow MOSAIC LAW.
The Jewish/Hebrew believers who came to Jesus as the promised messiah in the O.T./Judaic scriptures never understood that they must no longer have a "foundation" of "repentance" and that JESUS must now be their ONLY FOUNDATION.
Hebrews chapter 6 is explaining that the new teachings/principles about 'Jesus salvation' no longer require performing 'works of righteousness' in order to acheive cleanliness/"repentance" (spiritual purity) and that our ONLY FOUNDATION should be Christ Himself.......AND NEITHER should we have a simple "faith TOWARD God" (we should have a "FAITH FOR faith").....
Romans 1:17....."the righteousness of God is revealed through FAITH FOR FAITH".
Having a foundation other than CHRIST ONLY is "apostasy".....(having a foundation other than CHRIST ONLY makes it "impossible" to "restore" us to spiritual purity). ...."For God is not so unjust....".
When someone first comes to Jesus, they are a "babe in Christ" and are taught/"fed" with "milk". They are taught to do works of righteousness (have a foundation of repentance), but they are not taught the need to "move on" to maturity in Christ so that they will have ONLY JESUS as THEIR FOUNDATION.
The "law" was really only necessary for the 'CRIMINAL type' of human being.
At that time, God fully recognized that many believers today would make the same mistake of not 'moving on' to a mature ("more excellent", 1 Corin.12:31) devotion, so He ensured that this important explanation was in scripture for us to read, but it does not mean that those who never learn to move on to a deeper devotion based on the love FOR GOD ("the GREATEST of these", 1 Corin. 13:13) will end up in the lake of fire.....(for "GOD IS NOT SO UNJUST" Hebrews 6:10, saved through fire??) as to overlook all of the "works" they did and the love they showed to each other FOR HIS SAKE (it's not about love for EACH OTHER, it's about having TRUE love FOR GOD HIMSELF').....we are only to have regard/love for others AS we also have regard/love for ourself (I don't go around kissing myself or showering myself with gifts, I'm sane and emotionally stable).
So do not make it impossible to be restored to spiritual purity by not moving on to a deeper and truly PERSONAL relationship with Jesus. Learn of the "better things" that are part of salvation (Hebrews 6:9) and have a "faith for faith" (trust that God is a REWARDER, not a punisher', Hebrews 11:6).
1 Corinthians 3:2
"I fed you with milk, not solid food; for you were not ready for it; and even yet you are not ready".
"But solid food is for the mature, for those who have their faculties trained by practice to distinguish good from evil".
God had Pilate ask "What is truth?" (the OBJECTIVE truth about Jesus was declared by the state to be "INNOCENT", but He was sent to the cross because the people chose SUBJECTIVE TRUTH instead).....the question was not answered at the time.
We no longer have mere EXISTENCE in TIME, we have "LIFE"....REAL LIFE....LIFE eternal.
John 14:6...."I am THE WAY..."....."I am...the TRUTH"...."I am...the LIFE".
What was said in scripture 2,000 years ago was said to people that were alive 2,000 years ago (not all applies to us except the GOSPEL "doctrine of Christ).
