May I ask you a question please? What would you say to those people that say that the O.T. and the N.T. are not connected or related to each other? Myself I don't buy that, and I Believe that they are both related and connected to each other. In fact, a lot of O.T. prophesy has been fulfilled in the N.T. hasn't it, and some yet to be fulfilled? What would be the best answer, in your opinion and/or based upon your knowledge of both the O.T. and N.T. to those people who say there is no connection or that there is no relationship to each other. A lot of people today are making those kind of claims.
If I were in a foul mood I would say to them that they are brainless dolts wandering around spouting whatever liberal garbage has fallen in their ear!
"Myself I don't buy that, and I Believe that they are both related and connected to each other."
Me either! (Can you tell?) The OT and NT are so inner-twined that, from a Christian perspective, one is almost incomprehensible without the other. The OT is the PROMISE. The NT is the FULFILLMENT.
"What would be the best answer, in your opinion and/or based upon your knowledge of both the O.T. and N.T. to those people who say there is no connection or that there is no relationship to each other."
Well, I would say that there is almost 900 direct quotes or allusions to the OT in the NT
Here is a partial list of citation: http://www.blueletterbible.org/study/misc/quotes.html
and here is a list of parallel passages: http://www.blueletterbible.org/study/pnt/pnt08.html
... and that there are over 300 prophesies give in the OT which are explicitly fulfilled in the NT. You may find a better list, but here is one for your reference: http://www.vojo.com/rev/messianic_prophecies.htm
But in the end many people will not be convinced because they do not want to be convinced. They wouldn't believe even if they saw Jesus rise from the dead with their own eyes because the inconvenient truth of the Lordship of Jesus Christ interferes with their plans for their life. But by His grace some will be persuaded - so keep up your work for the Lord!
