ask for the ancient paths

Thus says the LORD, "Stand by the ways and see and ask for the ancient paths, Where the good way is, and walk in it; And you will find rest for your souls. But they said, 'We will not walk in it.' (Jeremiah 6:16)

The ancient paths…stand by their ways, seek and ask for them…where the good way is, walk in it.
What are the ancient paths? And why would the Lord exhort His people to walk in them? At this point in the history of Israel they had again wandered away from the Lord and His truth. And He had sent another prophet (Jeremiah) to 'put the people on notice so that they might be without excuse' (the grace and mercy of God shown to His people even though they had wandered so far off).
My take on the 'ancient paths' is that we are to stand by the ways, see and ask for and walk in the pure and uncompromised Truth of God - for the Word of the Lord is good. And Jesus Christ is the ancient path. He has always been and will forever be the Truth. We are encouraged to walk with Him in our lives, even to the point of dying to self and abiding in Him. And His promise to His people for following is that we shall find rest for our souls.
Yet, we live in an age today where the answer to the Lord's exhortation seems to be the same as the people of Jeremiah's time - 'we will not walk in it'. We want something new, something that man has conjured up…there is no pure truth - our wisdom has surpassed the 'ancient ways'…or so we believe.
Believers in the living Lord, here is our admonition - stand firm in His truth and in the power of His might and walk in the ancient paths.
