Could you give this some consideration? PLEASE

I am puzzled by fellow Christians who claim that the Old Testament is
defunct. The reason given so often is that Jesus was the lamb to
clear away its rules and regulations. If thats the case, and I have no
reason to doubt that He came to fulfill the law, could someone explain
to me what the following passages mean.

1) For truly, I say to you, till heaven and earth pass away, not an
iota, not a dot, will pass the law until all is accomplished.  Whoever
then relaxes one of the least of these commandments and teaches men
so, shall be called least in the kingdom of heaven; but he who does
them and teaches them shall be called great in the kingdom of heaven.
(Matthew 5:18-19 RSV)  Clearly the Old Testament is to be abided by
until the end of human existence itself.  None other then Jesus said
so.

2) All of the vicious Old Testament laws will be binding forever.  "It
is easier for Heaven and Earth to pass away than for the smallest part
of the letter of the law to become invalid."  (Luke 16:17 NAB)

3) Jesus strongly approves of the law and the prophets.  He hasnt the
slightest objection to the cruelties of the Old Testament.  "Do not
think that I have come to abolish the law or the prophets.  I have
come not to abolish but to fulfill.  Amen, I say to you, until heaven
and earth pass away, not the smallest part or the smallest part of a
letter will pass from the law, until all things have taken place."
(Matthew 5:17 NAB)

3b) "All scripture is inspired by God and is useful for teaching, for
refutation, for correction, and for training in righteousness..."  (2
Timothy 3:16 NAB)

3c) "Know this first of all, that there is no prophecy of scripture
that is a matter of personal interpretation, for no prophecy ever came
through human will; but rather human beings moved by the holy Spirit
spoke under the influence of God." (2 Peter 20-21 NAB)

4) Jesus criticizes the Jews for not killing their disobedient
children according to Old Testament law.  Mark.7:9-13  "Whoever curses
father or mother shall die"  (Mark 7:10 NAB)

5) Jesus is criticized by the Pharisees for not washing his hands
before eating.  He defends himself by attacking them for not killing
disobedient children according to the commandment: He that curseth
father or mother, let him die the death.  (Matthew 15:4-7)

6) Jesus has a punishment even worse than his father concerning
adultery: God said the act of adultery was punishable by death. Jesus
says looking with lust is the same thing and you should gouge your eye
out, better a part, than the whole.  The punishment under Jesus is an
eternity in Hell.  (Matthew 5:27)

7) Peter says that all slaves should be subject to [their] masters
with all fear, to the bad and cruel as well as the good and gentle.
This is merely an echo of the same slavery commands in the Old
Testament. 1 Peter 2:18

8) Did not Moses give you the law, and yet none of you keepeth the
law" (John7:19) and For the law was given by Moses,..." (John 1:17).

9) ...the scripture cannot be broken. --Jesus Christ, John 10:35

Thankyou for your time.
