Do your best to present yourself to God as one approved, a worker who has no need to be ashamed, rightly handling the word of truth.
The Apostolic Scriptures join in the Hebrew text with the idea of purification by the waters of the red heifer. People came early to Jerusalem for the Passover in order to purify themselves (John 11:55), It is noted that Paul himself, after a long trip out of the Land purified himself in that manner along with four other believers from the Messianic congregation in Jerusalem. He even paid for the expense, which required the offering of animals (Acts 21:24, 26).
Believers usually assume that Yeshua’s death on the cross replaced any and all form of offering, but there are no Scriptural grounds for that. The book of Acts (as well as other historical literature) tells us that the disciples continued attending the Jerusalem Temple’s regular morning and evening prayers which involved offerings (Acts 3:1), that they actually constantly hanged around the Temple (Acts 2:46). Records even show us that many of the priests were believers (Acts 6:7) and that believers were in control of the city (Acts 5:26; Acts 6:7).The only reason the believers stopped attending the Temple’s prayers and services was because of persecution. A few years before the Roman invasion an evil High-Priest martyred James the Just (the leader of the Hebrew believers and brother of Yeshua) and as a result as Yeshua predicted it, the believers were kicked out of the synagogues and of the Temple (John 16:2) which was eventually destroyed in 70 C.E. by the Roman General Titus.
The book of Hebrew attests to the need of the red heifer‘s water purification in these words, For if the blood of goats and bulls, and the sprinkling of defiled persons with the ashes of a heifer, sanctify for the purification of the flesh, how much more will the blood of Messiah, who through the eternal Spirit offered himself without blemish to God, purify our conscience from dead works to serve the living God (Hebrews 9:13-14). Our author here validates the efficaciousness of the blood of Messiah to purify our conscience with the efficaciousness the waters of a red heifer to sanctify the flesh in order to enter Jerusalem and the Temple. The argument here is invalidated if the purification through the water of the red heifer has become obsolete.
Offerings were never intended for the sanctification of the conscience; only for the flesh. Only God through the Messiah cleans the conscience and since the work of Messiah was completed before the foundation of the earth along with all the works of God, this principle has at work through people being justified even in the times that precede Yeshua’s manifestation on earth (Genesis 15:6; 1:Peter 1:20; John 14:6).
May Messiah daily clean our soul form sin, iniquity and unrighteousness, but mostly from teachings that tend to invalidate and re-interpret the Word in a way He never intended it to be.
