Matthew 5:1-2,17-20

Now when He saw the crowds,
He went up on a mountainside and sat down.
His disciples came to him,
and he began to teach them, saying:
. . . 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.
I tell you the truth,
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.
Anyone who breaks one of the least of these commandments
and teaches others to do the same
will be called least in the kingdom of heaven,
but whoever practices and teaches those commands
will be called great in the kingdom of heaven.
For I tell you
that unless your righteousness
surpasses that of the Pharisees and the teaches of the law,
you will certainly not enter the kingdom of heaven.
(Matthew 5:1-2, 17-20) NIV
