"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.’"
Just as a traveler would be foolish to set out on a journey without first inquiring as to which road he should take, so we would be foolish to embark on a spiritual journey without determining the right way to go. God wants us to know Him and walk with Him. He has given us His word to study and learn "where the good way is". Once we have found it we find soul rest. But only if we obey what we have learned. "When you have found the good way, go on in it, you will find abundant recompence at your journey's end. But if men will not obey the voice of God and flee to his appointed Refuge, it will plainly appear at the day of judgment, that they are ruined because they reject God's word." (Matthew Henry)
