This is certainly confusing.

I find this a bit confusing.

Luke 16:16-17(NKJV)

“The law and the prophets were until John. Since that time the kingdom of God has been preached, and everyone is pressing into it. 

And it is easier for heaven and earth to pass away than for one tittle of the law to fail.

 The first part says "the law and the prophets were until John…".  That makes it sound as if the law ended doesn't it?

But then the last part says "And it is easier for heaven and earth to pass away than for one tittle of the law to fail. " which makes it seem as of the law continues.

Which is it? 

Well Jesus said "I didn't come to replace the law but to fulfill it." or something close to that. 

Even that statement leaves a bit of ambiguity.  The phrase "fulfill it" to some might give it a past tense feel to the statement if that makes sense.

Something to ponder.
