The OT brought us to faith. As a child we had to learn about God and his expectations and the need for Christ. Galatians

The NT gives us the spiritual realities of the physical examples of the OT. We now live by faith in the spirit relying on Christ for our relationship with God instead of an attempt at perfectly performing a law.

All glory to God

A testament is a testimony of witness. One precedes Messiah, while the other proceeds. There is a saying, "The new is in the old concealed, the old is in the new revealed". If you remember that, you will pretty much have it. The Old Testament (or Tonakh) was written to prophesy the first and second coming of Messiah.

Yeshua fulfilled the requirements for the redemption of man, thus turning the relationship between G-d and man into one of fellowship and not via earthly priests and rituals.

John 5:39

Jesus said, "You search the Scriptures, for in them you think you have eternal life; and these are they which testify of Me."

With Yeshua now THE Lamb that takes away the Sin of the world, a new order was established--not based on the Law, fading traditions, or ritual sacrifice, but rather on the finished work of Yeshua HaMashiach (Jesus the Messiah). See Hebrews 9

Hebrews 9:11

But Christ came as High Priest of the good things to come, with the greater and more perfect tabernacle not made with hands, that is, not of this creation.

The OT is not replaced by the NT.

They have as their theme, the same things.

Jehovah God's principles are championed in both.

The NT records the fulfillment of about 200 prophecies about the Messiah.

They go together! One is not better than the other. Nor does one replace the other. God's principles are the same in both. In the NT he directs that we follow them out of love & appreciation of his righteousness, instead of merely to fulfil a set of laws. The multiple purpose of those many laws are interesting, in that they showed theIsraelites just how far from perfection that they were (& everyone else, too), because no one was able to live up to them. This proved mankind's need for the Messiah. Such laws were done away with. But, not all of the laws:

" . . . 'Hear O Israel! Jehovah our God is the one and only God. And you must love him with all your heart, and soul, and mind, and strength . . . 'You must love others as much as yourself.' No other commandments are greater than these." Mark 12:28-31, see also Luke 10:25-27

It takes time to both teach, & then to learn. When the Israelites first received the Law Covenant, it was the *first* time they had such commandments to follow. Now, they were definate, & in writing, instead of based on the individual consciences of people. When Jesus came, it was no surprize, and they were looking for their Messiah. However, they had their own ideas of what he should do for them, & these did not match God's plans. So, the majority did not recognize Jesus, even though he fulfilled every prophecy about him, to the letter.

Thus, God left the nation of Israel, who had turned their backs on him. Another group began with individual Israelites, who chose to follow God, instead of the Jewish religious leader's preconcieved ideas.

Both the OT & the NT together give the history of God with mankind --all of the most pertinent parts-- for us to be able to learn God's character, wisdom, fairness, & love.

What Is the Value of the “Old Testament”? :

- Is the “Old Testament” Still Relevant?

- It Was “Written for Our Instruction”

You make the statement:

"He knew, from the first day of creation, when the last day would occur."

But, Jehovah God is a person of purpose. Rather than planning every detail out long into the future, he decides to do something, & starts working toward that end. When he created the earth & mankind, & some rebels 'threw monkey wrenches' into his purpose --still in the process of unfolding-- he *then* decided how he'd handle it . . .

Just because someone is strong enough to lift 200 lbs. does not mean that he is always carrying 200 lbs. around.

Just because one may be able to read a large book from cover to cover & retain what it says, does not mean that he reads every book in that manner.

A man about to embark on a long journey, may have at his disposal a telephone or email, yet choose to use neither in order to find out in advance about the weather.

Likewise, just because Jehovah God is all-knowing, this does not mean that he was aware during creation that rebels from both the spirit realm, & humanity, would make such a horrid mess of everything! However, Jehovah being a person of Grand Purpose, began leading that dire situation, back in the right direction . . .

Genesis 3:15 is his first prophecy regarding his heavenly kingdom government, which will cleanse & restore everything back to perfection.

One without the other, is unimaginable!

The OT & NT are equally important!

It's not every day I get to see someone so blatantly show their lack of faith regarding the new covenant and the new covenant law of faith.

God did not "change the laws." What God did was end the old covenant and institute the new covenant; a better covenant with better promises.

When the old covenant went, so also went all the conditions and requirements of that covenant.

If you understood the new covenant and the law of faith, you would not be asking this question.

.

I think both are relevant. I think some of the Old Testament laws are irrelevant from a historical context in today's world (ex some of the communicable diseases they had aren't prevalent in today's world), however, the ten commandments I do think are a guide for how Christians should live.

The OT says that not one punctuation mark in it shall be changed, so the NT is invalid. You can't believe in both the OT (than no additions shall be made) and the NT (an addition to the OT), unless you don't understand what you claim to believe in.
