Perhaps you should read and study your Bible before you make an ass out of yourself. Everything I presented can be documented by Book, Chapter and Verse. Who should we believe........"you" or the Holy Scriptures?
Why the Law of Moses is no longer in effect: The Holy Scriptures consist of 2 major parts.....the O.T. and the N.T.
A testament is a will or covenant. Thus, we have the Old Will and the New Will from God.
This change in wills is documented in detail (Hebrews 1:1-2). God no longer speaks to man through prophets (as He did under the Old Law) but rather through the words of Christ Jesus. Jesus Himself stated as much, "He that rejecteth Me; and receiveth not My Words has one that judges him; the word that I have spoken; the same shall judge him on the last day." -- John 12:48 The Old Law had no solution for men who were continually sinning ..........the best it offered was the blood of bulls and goats to hide sin from one season to the next, "........for it is impossible for the blood of bulls and goats to take away sin." -- Hebrews 10...explains in detail why the old law existed, it was but a shadow of things to come, until the seed of Abraham came, Jesus was that seed that ushered in the N.T. kingdom of God......the sacrifice of Jesus mirrored the promise made to Abraham (Genesis 22:8), "God will provide for Himself the lamb for a burnt offering.....MY SON." The apostle confirms that Jesus was that offering (Gal. 3)
This change in testaments/wills is documented and foretold in the O.T. -- Jer.31:31-34 God stated through the prophet Jeremiah the new testament/will will be different from the one delivered to Moses on Mt. Sanai.
Why would God change the law....did He change His mind? Absolutely not....God is unchanging from the beginning to the end (Malachi 3:6, "I am the Lord, I change not........" Why the change? God did not change His mind.........both testaments were planned even before the worlds were created, before time itself began (1 Peter 1:19-20, 2 Tim. 1:9, Thess. 2:13-14)
The apostles of Christ were speaking for the Christ after His ascension into heaven where He is seated at the right hand of the Father on the Throne of David as ruler of Spiritual Jerusalem...i.e. the church/kingdom of God/Christ (Acts 2:36, Jesus is both Lord and Christ of His kingdom). The Apostles were commissioned by Jesus before His death to receive power from heaven in the form of a helper....the Holy Spirit of Truth/Holy Ghost/Spirit in order to establish the N.T. church's doctrine as directed by Jesus from Heaven (John 16:13)
The Apostles tell us that not only was there a change in testaments/covenants......but a change in the Priesthood, where Jesus is the High Priest will all members being themselves part of a royal priesthood. No middle man needed to approach the throne of the Christ (Heb. 5:1-10, 1 Peter 2:9, Rev. 1:6) all members are equal.......no laity separated from the clergy.
The Apostle tells us........when there is a change in the priesthood there must be a change in testaments/covenants (Heb.7:11-17)
There was a change in sacrifices (Heb. 9:16-28, 10:1-8) Jesus fulfilled the requirements of the Old Law (Matthew 5:17-18), Paul the Apostle tells us that Jesus nailed the Old Law to His sacrificial cross (Col.2:14). The Old Law was put death on the cross along with Jesus Christ (Eph. 2:15)
Those who still practice their faith under the Old Law are worshiping in vain, "You have been severed from Christ, you who are seeking to be justified by the law (of Moses); you have fallen from grace." -- Gal. 5:4.
