Paul said we do not void out the law through faith,but we establish the law,and the law is spiritual,holy,just,and good,the laws of love,moral laws.
Jesus took the physical ordinances of Israel away,including all the laws that are not part of laws of love,moral laws,which are spiritual laws.
We go by the 2 greatest commandments love God,and love people,and all the prophets and law hang on those 2 laws.
Love people.
Jesus said a new commandment I give you that you love one another as I have loved you,and love works no ill towards their neighbor,therefore love is the fulfilling of the law,and the ten commandments are love towards God and people,so they are spiritual laws and did not pass away.
Love God.
The Lord knows them that are His having this seal,let everyone that names the name of Christ depart from iniquity,and if you do not continue in the goodness of God you will be cut off like the Old Testament,and do not depart from the living God by the deceitfulness of sin,and abstain from fleshy lusts that war against the soul,and lay aside every weight of sin that so easily besets us,and blessed is the man that endures temptation,does not sin,for he shall receive the crown of life given to all those that love Christ.
Jesus said until heaven and earth pass away not one jot or tittle shall in no wise pass from the law until all is fulfilled.
Zec 14:9 And the LORD shall be king over all the earth: in that day shall there be one LORD, and his name one.
Isa 11:9 They shall not hurt nor destroy in all my holy mountain: for the earth shall be full of the knowledge of the LORD, as the waters cover the sea.
Zec 14:16 And it shall come to pass, that every one that is left of all the nations which came against Jerusalem shall even go up from year to year to worship the King, the LORD of hosts, and to keep the feast of tabernacles.
But Jesus did not fulfill all the law yet,which must be done on earth,for He still has to fulfill the law of being perfect King on earth,which is what the millennial reign of Christ is about,Jesus fulfilling the role of perfect King on earth,and after the millennial reign then heaven and earth shall pass away,and there will be a new heaven and a new earth,where sin has never been and sin will never be,and the former earth shall not be remembered,nor come to mind,for it is associated with sin and rebellion.
People that think the millennial reign is not on earth with Jesus physically ruling is wrong for Jesus must rule on earth,for the law must be fulfilled on earth,and He is the perfect High Priest,saint,Prophet,sacrifice,and whatever He had to fulfill,and He is King now,but He must fulfill the role of King on earth to fulfill the law,then heaven and earth shall pass away.
They say there are 600 physical laws,but I do not think Jesus had to fulfill those,but had to fulfill the laws of love,moral laws,that they did not have the power to completely obey because the Spirit was not given,and that is why God gave them physical laws that they did have the power to keep,so if they had the power to keep the physical laws then why would Jesus have to fulfill them,but they did not have the power to keep the spiritual laws perfectly,so Jesus had to fulfill them,for we only have access to heaven by obeying love God,and love people,the spiritual laws,and the physical ordinances were contrary to us for they had no bearing on spiritual salvation,so Jesus only had to fulfill the law that had to do with spiritual laws that no person could keep perfectly.
