"He disarmed the rulers and authorities and put them to open shame, by triumphing over them in him. Therefore let no one pass judgment on you in questions of food and drink, or with regard to a festival or a new moon or a Sabbath. These are a shadow of the things to come, but the substance belongs to Christ." - Colossians 2:15-17 ESV
The Hapax Legomenon (unique word) here is 'new moon'. The Hebrew calendar is a lunar calendar and worship was on a lunar schedule.
Festival, New Moon and Sabbath = Recreation, Cycles (or marking the passage of time) and Rest
"And it shall come to pass, that from one new moon to another, and from one sabbath to another, shall all flesh come to worship before me, saith the LORD." - Isaiah 66:23 KJV
"Likewise the people of the land shall worship at the door of this gate before the LORD in the sabbaths and in the new moons." - Ezekiel 46:3 KJV
These two passages are prophetic in nature. Many people don't mark the passage of time by worship.
At the time this is written we are closing out a month and will soon begin another. What does that mean to us?
I often look at the month coming before it arrives. I look at my birthday list and pray. I think about appointments. I gauge needs. I pay or mentally put aside money for bills that come in monthly cycles.
My devotional life is a portal into worship. It isn't me trying to better myself. It is the exploration of God's mind.
Oppression leaves a depression that is painful. An oppressor seek to exploit and to do that he or she must isolate, accuse and gain dependency. To do that integrity must be destroyed so that accusation will be internalized and isolation will be reinforced. Then exploitation can continue.
A worshipper can't be isolated. God is there. A worshipper knows accusations can't isolate unless they are internalized.
If worship has been disqualified in our lives we have believed a lie. It might be a lie about God or about ourselves... or both. It takes humility to worship. Lets humble ourselves and enter in by faith. God's light will banish the darkness. His Word will be a light for our path and a lamp for our feet on the path that echoes with praise.
In God's economy of grace we are not in bondage. We are not forced to regulate ourselves (or others) in recreation or rest. We each mark the passage of time differently and our emphasis may be different. In truth, from God's perspective, the substance of these things rests in Christ. When He becomes the focus then worship is incorporated into our cycles and our Sabbath.
