The Sabbath is a regularly recurring holy day. Keeping it is basic to a Christian's relationship with God. When He rested on the seventh day at creation, God set it apart, reaffirming it to Israel in the wilderness by giving it as the fourth of the Ten Commandments in the section Jesus summarized as showing how to love God. Idolatry and Sabbath breaking were largely responsible for Israel's downfall. Jesus, the Lord of the Sabbath, clearly taught that the Sabbath is made for man. He and His apostles kept it, and it is nowhere abrogated either by command or example in the New Testament. The prophets show the Sabbath being kept after Christ's return.
