I believe you’re wrong that Jesus commanded us to follow all of the old testament laws.

Jesus came into our time as was prophesied through the law and the prophets.

Matthew 5:17 NKJV
“Do not think that I came to destroy the Law or the Prophets. I did not come to destroy but to fulfill.

Strong’s g4137.  To fulfill:

– Lexical: πληρόω
– Transliteration: pléroó
– Part of Speech: Verb
– Phonetic Spelling: play-ro’-o
– Definition: to fill, fulfill, complete.
– Origin: From pleres; to make replete, i.e. (literally) to cram (a net), level up (a hollow), or (figuratively) to furnish (or imbue, diffuse, influence), satisfy, execute (an office), finish (a period or task), verify (or coincide with a prediction), etc..
– Usage: accomplish, X after, (be) complete, end, expire, fill (up), fulfil, (be, make) full (come), fully preach, perfect, supply.

Jesus came not to destroy the Law and the Prophets but to fulfill them. In fact, the ceremonies, sacrifices, and other elements of the Old Covenant were “only a shadow of the good things that are coming—not the realities themselves” (Hebrews 10:1). The tabernacle and temple were “holy places made with hands,” but they were never meant to be permanent; they were but “copies of the true things” (Hebrews 9:24, ESV). The Law had a built-in expiration date, being filled as it was with “external regulations applying until the time of the new order” (Hebrews 9:10).

In His fulfillment of the Law and Prophets, Jesus obtained our eternal salvation. No more were priests required to offer sacrifices and enter the holy place (Hebrews 10:8–14). Jesus has done that for us, once and for all. By grace through faith, we are made right with God: “He forgave us all our sins, having canceled the charge of our legal indebtedness, which stood against us and condemned us; he has taken it away, nailing it to the cross” (Colossians 2:14).

There are some who argue that, since Jesus did not “abolish” the Law, then the Law is still in effect—and still binding on New Testament Christians. But Paul is clear that the believer in Christ is no longer under the Law: “We were held in custody under the Law, locked up until faith should be revealed. So the Law became our guardian to lead us to Christ, that we might be justified by faith. Now that faith has come, we are no longer under a guardian” (Galatians 3:23–25, BSB). We are not under the Mosaic Law but under “the law of Christ” (see Galatians 6:2).

2 Corinthians 5:17 NKJV
Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new.

Romans 7:14 NKJV
For we know that the law is spiritual, but I am carnal, sold under sin.

Hebrews 7:12 NKJV
For the priesthood being changed, of necessity there is also a change of the law.

Romans 8:13 NKJV
For if you live according to the flesh you will die; but if by the Spirit you put to death the deeds of the body, you will live.

Luke 24:44-45 NKJV
Then He said to them, “These are the words which I spoke to you while I was still with you, that all things must be fulfilled which were written in the Law of Moses and the Prophets and the Psalms concerning Me.” [45] And He opened their understanding, that they might comprehend the Scriptures.

Romans 8:3-4 NKJV
For what the law could not do in that it was weak through the flesh, God did by sending His own Son in the likeness of sinful flesh, on account of sin: He condemned sin in the flesh, [4] that the righteous requirement of the law might be fulfilled in us who do not walk according to the flesh but according to the Spirit.

The law (the Mosaic Law/Torah) spoke of Christ to come primarily by serving as a foreshadowing, tutor, and prophetic witness that pointed forward to a future Messiah. It operated through sacrificial systems, ceremonial ordinances, and moral requirements that highlighted the need for redemption, ultimately aiming to lead people to faith in Christ. 

How the Law Spoke of Christ:

As a Tutor or Guardian: According to Galatians 3:24 Bible.com, the law acted as a guardian or “schoolmaster” to lead people to Christ, protecting and preparing them until the Messiah came.

Through Sacrifices and Shadows: The sacrificial system, circumcision, the paschal lamb, and other ordinances in the Mosaic law were types, or “shadows,” that foreshadowed the final, perfect sacrifice of Christ.

By Defining Sin: The law served as a standard to define sin, showing humanity its inability to be righteous on its own and revealing the necessity for a Savior.

Through Prophecy: Moses specifically recorded direct prophecies and promises about the coming Messiah who would redeem humanity.

As the Goal of the Law: Christ is the fulfillment or “goal” of the law, which means the law was designed to lead to Him.

If Christians today look back at the law of Moses for justification by any means is to place trust in ourselves. These people are the modern Christian Pharisees of today.

Hebrews 10:38 NKJV
Now the just shall live by faith; But if anyone draws back, My soul has no pleasure in him.”

The “just” man is one not in appearance only, but in reality; not by his obedience to the law, but by the obedience of Christ.

Christ plus nothing!

All of Him and none of me!
