Joh 7:23 If a man on the sabbath day receive circumcision, that the law of Moses should not be broken; are ye angry at me, because I have made a man every whit whole on the sabbath day?
Was Jesus teaching that the law of Moses had ended? I don't think so. Jesus is our Rabbi....that is the true teacher of all things Jewish and Israelitish (ie Torah, Prophets, and Writings). We are spiritual Israel who have faith in Jesus and have grace poured out on us.
Jer 31:33 But this shall be the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
Heb 8:10 For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people:
God writes His Laws on our hearts and puts them into our minds. What Laws you ask? Through the Holy Spirit and the renewing of your mind, that is reading and studying Torah and Prophets and Writings (ie. OT). The Holy Spirit will bring to mind those things you have searched out in the scriptures at just the right moments when they are needed. You have heard garbage in garbage out. The Torah is not garbage but treasures.
Luk 12:48 But he that knew not, and did commit things worthy of stripes, shall be beaten with few stripes. For unto whomsoever much is given, of him shall be much required: and to whom men have committed much, of him they will ask the more.
Surely, all things Torah is a matter of faith and grace with the aid of the Holy Spirit to guide you. However, if you kick the pricks, that is shut off what little light may come in, you will abide in darkness.
But, Joh 6:44 No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day.
How important is the Father to you? How important is the renewed covenant to you? Jesus is the mediator between the old covenant and the new covenant. He is our bridge to entering everlasting life. He is also our teacher, that is of the true religion of spiritual Israelites. Not Paul and the twisted interpretation that the Law is bad and therefore to be avoided. Paul is misunderstood, as I share previously.
To fully answer your question, I am not a teacher to believers who do not obey God's commandments. To those who obey God's commandments, we are iron sharpening iron to each other.
