Then your teachers were ignorant of what Jesus actually said:-
matt5: 17 “Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. 18 For truly I tell you, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished. 19 Therefore anyone who sets aside one of the least of these commands and teaches others accordingly will be called least in the kingdom of heaven, but whoever practices and teaches these commands will be called great in the kingdom of heaven. 20 For I tell you that unless your righteousness surpasses that of the Pharisees and the teachers of the law, you will certainly not enter the kingdom of heaven.
matt24: 35, Heaven and earth will pass away, but my words will never pass away.
Jesus was asked about the greatest commandment and he quoted the OT Deut 6:5 and Lev19:18
As these two sum up the whole of the law that your teachers were saying one does not have to obey.
This here is the crux of the matter I believe and the same scripture I thought to post and you beat me to it. Good job, Brother.
I'm not sure that I personally understand why some would seek to be loosed from the law of the OT? The 10 commandments are words to live by. To press in and grow in Christ.
I actually had the thought earlier today that, once we are saved, the sanctification and purification process begins, and everyone knows it is a thing which is a process and takes time. But!! Let us not be confused about how it takes place, ok?
Does the Lord who sanctifies me and purifies me, do this of Him self? ...and it is a gift to me? A grace? This is not cut and dry clearly. Do I sanctify myself? Probably not, or at the very least I may only initiate it and thereby participate in it, in that way.
Scripture states, if you love me, you will keep my commandments. So that means that we are to put forth effort and action towards and to contribute to our own sanctification, correct? For example, I get saved and read more, pray more...even help the poor more...but continue to indulge in my favorite or two worldly sins. Will I go to heaven? Will Jesus show up one day and supernaturally transform me and my heart into a perfect being? He might...He could. But consider this,
scripture says that there will be no liars in heaven. Scripture says there will be no thieves in heaven. So we better make the choice to not speak that (so called) little white lie. Or keep the extra money which the big bad corporation accidently handed me at the check out counter. ...on earth as it is in heaven? So I can't be a liar when Jesus shows up. I can not be a thief at heart (if the conditions are right). Not being a liar or thief (right now) means not having the heart to do such things. I submit to you Brothers and Sisters, that we are very much responsible for our own sanctification as God is. If we are upright Christians who give at the church and to the poor, and walk in His Spirit, in love towards all, then we succumb ourselves willingly to temptations to lie, to steal, to cheat on our spouse's even in thought and don't realize that this is a stain on our wedding gown...then we might just be in big trouble...then maybe we need to study more.
When Jesus said, my Love covers a multitude of sins, He didn't say that so that we can go on sinning and not committing our life to him 100%. To the Lord, being guilty of even the smallest transgression of the law is to be guilty of all of it...so there is no loophole there! God will not be mocked.
If God does not change, then how could the OT be null and void? That is an absurd notion. Of course the Lord wants us to obey the law. It is obeying Him and a proclamation of our love for Him when we listen to our conscience and...do not fall for the temptation. Doing the right thing pleases the Lord. It is worship and pressing in and the Lord rewards such behavior and commitment. .
If anyone has never broke down and wept because of their own shortcomings, then I would think that the same does not take scripture or the Lord seriously.
Oh Lord, make in me a contrite heart.
