A shadow of things to come

Rule number one in biblical exegesis: Let the Bible define the Bible. Compare the context of all similar word or phrase usages in other verses. Use Strong’s Concordance Hebrew and Greek dictionary numbers to confirm that we are comparing apples to apples.
Colossians 2:17; Which are a shadow G4639 of things to come G3195; for G1161 the body is of Christ.
Compare:
Hebrews 10:1; For the law having a shadow G4639 of good G18 things to come G3195, and not the very image of the things,...
If you listen carfully, you will notice preachers rarely if ever mention Colossians 2:17 as the end of the sentence begun in Colossians 2:16. Colossians 2:17 does not fit Christian theology that the biblical holydays have any future significance i.e. a shadow of things to come. The biblical holydays are divided between the Spring Harvest and the fall Harvest; or to say it another way, the first harvest and the final Harvest i.e. the first coming and the second coming. Passover-Crusifixion, day of Firstfruits-Resurection (Jesus was the first fruit of the dead i.e. an incorruptible body), fifty days later Penecost-the Holy Spirit in the upper room of the Holy Temple (where else would any Jew be on a Biblically Commanded Holyday). Those first harvest Holydays are now a commemoration of prophecy fulfilled. The final harvest Holydays are shadows of things yet to come; Rosh Hashanah, Biblically known as Yom Teruah (Day of Blowing), The Feast of Trumpets, the final trump, the second comming, "The Day of the LORD". Next is Yom Kippur, Day of Atonement-The Final Judgment for those not in good standing i.e. not having a personal relationship with God AND the Atoning covering of the blood of the Lamb of God. Followed by the Feast of Booths also called the Feast of Tabernacles-The Wedding Celebration also the phrase “He tabernacled among us†John 1:14; And the Word was made flesh, and tabernacled G4637 among us, ... alludes to Jesus being born during this festival. Not the third confirmation day of the winter solstice/Roman Saturnalia/Roman Catholic Christmas. Please read about these things to confirm whether they are true or not. Google biblical holydays.
