The Sabbath Day was fulfilled in Jesus. Just like we no longer sacrifice because He is the Sacrifice, so we no longer worship on the Sabbath because Jesus is our Sabbath. He is our rest. Colossians 2:16 says "Therefore do not let anyone judge you by what you eat or drink, or with regard to a religious festival, a New Moon celebration or a Sabbath day" So now we primarily worship on the Lord's Day which is the day He rose from the dead. Of course, it is the Lord's Time as well so any day is appropriate for worship.
