Now how about answer the points of the post you responded too. Because either you are saying Jesus is a liar or you are misunderstanding a a lot more than you think.
Because according to Jesus we are to let our light shine before men that they see our good works that our Father be glorified. In respect to this He said that, "Until Heaven and earth pass away not one jot or tittle shall pass from the law until all is fulfilled." Therefore he said in respect to the law, he mentioned, "Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven". And then in respect to that he says, "For I say unto you". That means as in verse 18 that what follows is directly related to what is about to be said. The use of the word "for" dictates this as does the word "that". So in respect to being called least in the Kingdom of Heaven for breaking one of these least commandments, and teaching men so, except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven.
So what does it mean to be called least in the Kingdom of Heaven?
It means We shall in no case enter therein if we shall break one of these least (smallest) commandment and teach men so.
By the way, If there are commandments that are considered least, small in the mind and heart of God that means there are greater ones also.
Deut 6:5 And thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might.
Lev 19:18 Thou shalt not avenge, nor bear any grudge against the children of thy people, but thou shalt love thy neighbour as thyself: I am the LORD.
For all the law and the prophets hang, depend on these two.
Matthew 22:37-40
Incidentally how can we be under that which now has become part of us through Christ?
For God has said His Law is in our hearts and in our minds, His Word in our hearts and mouths that is the word of faith in which we preach.
Matt 5:16 Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.
Matt 5:17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
Matt 5:18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
Matt 5:19 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.
Matt 5:20 For I say unto you, That except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven.
Matt 5:21 Ye have heard that it was said by them of old time, Thou shalt not kill; and whosoever shall kill shall be in danger of the judgment:
