The worshipping on Sunday stemmed from “the Way” found in the NT church where they celebrated the resurrection of Jesus instead of the end of creation. Throughout the Bible is found 2 covenants, a covenant of works which was given in Genesis 2, then the second covenant was found as early as Genesis 3, the covenant of grace. God gives a promise based on no merit.

The covenant of works ends at the resurrection of Jesus, for he had satisfied the law’s righteous demands. The second covenant will end at his second coming, when he makes all things new.

This change of covenant led to the change in the day of worship.

The importance of the 1st covenant ending, is that God's promise to bless was no longer tied to man’s ability to keep the commandments. The whole aspect changes, you do good works out of a thankful heart. This isn’t a new concept, for King David recognized it, as well as the minor prophets, yet that is now the main message, to live a life of thanksgiving for what Jesus had done, that’s why we obey, not for earthly blessings, though that may be a cause-effect that happens as a byproduct, but that is our command.
