Being all-powerful, Yahweh did not need to rest on the seventh day. Being sinless, neither did Yahshua need to be immersed for His sins. But both did so as examples for the people of Yahweh.
By resting on the seventh day, Yahweh created and established the Sabbath as the crowning achievement of His creation. What could be more important for us than to observe a day that Yahweh Himself observed. No other day carries that special distinction or honor.
