What is the Lord’s day?

The phrase “the Lord’s day” appears only once in the Bible, in Revelation 1:9-10, where the apostle John wrote, “I, John, both your brother and companion in the tribulation and kingdom and patience of Jesus Christ, was on the island that is called Patmos for the word of God and for the testimony of Jesus Christ. I was in the Spirit on the Lord’s Day, and I heard behind me a loud voice, as of a trumpet.” This passage identifies the time when John received his prophetic vision but does not explicitly define which day of the week “the Lord’s day” refers to.

Scripture offers practical wisdom on The Lord’s day for believers seeking a deeper walk with God.

Over the centuries, many have assumed that “the Lord’s day” means Sunday, the first day of the week. However, the Bible itself-not church tradition or human reasoning-must be the authority for interpreting Scripture. When we search the Word of God, we find that the “Lord’s day” is not Sunday but the seventh-day Sabbath, established at Creation and reaffirmed throughout the Bible as the day belonging to the Lord.

The New Testament contains only eight references to the first day of the week, and none of them identify it as sacred or as belonging to the Lord. In none of these passages-Matthew 28:1; Mark 16:1-2, 9; Luke 24:1; John 20:1, 19; Acts 20:7; and 1 Corinthians 16:2-do we find any command or example of Sunday being called holy or being set apart for worship.

In contrast, the Bible consistently identifies the seventh day as the special day of the Lord. From the beginning of time, God blessed and sanctified the seventh day as the memorial of His creation. Genesis 2:3 declares, “Then God blessed the seventh day and sanctified it, because in it He rested from all His work which God had created and made.”

This verse reveals three divine acts that make the Sabbath unique: God blessed it, sanctified it (set it apart for a holy purpose), and rested upon it. No other day of the week has these divine distinctions. Thus, the Sabbath was not a ceremonial or temporary institution but a perpetual sign of God’s creative authority and love for humanity.

The Sabbath as the Lord’s Day

When the Lord gave the Ten Commandments to Israel, He reaffirmed the sanctity of the seventh day: “Remember the Sabbath day, to keep it holy. Six days you shall labor and do all your work, but the seventh day is the Sabbath of the Lord your God. In it you shall do no work: you, nor your son, nor your daughter, nor your male servant, nor your female servant, nor your cattle, nor your stranger who is within your gates. For in six days the Lord made the heavens and the earth, the sea, and all that is in them, and rested the seventh day. Therefore the Lord blessed the Sabbath day and hallowed it” (Exodus 20:8-11).

Notice that the Sabbath is not called “the Sabbath of the Jews,” but “the Sabbath of the Lord your God.” It is the Lord’s own day, set apart as a memorial of His creative power. The commandment begins with the word “remember,” indicating that it was established long before Sinai-in fact, at the very creation of the world.

Isaiah also confirmed this truth when he wrote, “If you turn away your foot from the Sabbath, from doing your pleasure on My holy day, and call the Sabbath a delight, the holy day of the Lord honorable, and shall honor Him… then you shall delight yourself in the Lord” (Isaiah 58:13-14). Here, God Himself calls the Sabbath “My holy day.” There is no biblical record of Him ever transferring this title to any other day of the week.

Jesus and the Lord’s Day

Jesus’ own words also confirm that the Sabbath is the Lord’s Day. He declared, “The Son of Man is Lord also of the Sabbath” (Mark 2:28). This statement follows His explanation that “the Sabbath was made for man, and not man for the Sabbath” (Mark 2:27). The Sabbath was created for the benefit of all humanity-not for one nation or one time period. It was given at creation, before the existence of the Jewish nation, as a gift for all people to find rest, renewal, and fellowship with their Creator.

By calling Himself “Lord of the Sabbath,” Christ identified this day as His own. He is the One who instituted it, blessed it, and kept it. Therefore, the “Lord’s day” can rightly be understood as the Sabbath day-the day that belongs uniquely to the Lord Jesus.

Some claim that Jesus abolished the Sabbath or transferred its holiness to Sunday after His resurrection. But Jesus made it clear that He did not come to destroy the law: “Do not think that I came to destroy the Law or the Prophets. I did not come to destroy but to fulfill. For assuredly, I say to you, till heaven and earth pass away, one jot or one tittle will by no means pass from the law till all is fulfilled” (Matthew 5:17-18).

He fulfilled the law by perfectly keeping it and showing its true spiritual meaning, not by eliminating it. The Ten Commandments, including the Sabbath command, remain binding upon all believers as God’s moral law (Romans 3:31; James 2:10-12).

The Lord’s Day in Prophecy and the Early Church

When the apostle John received the vision of Revelation on “the Lord’s day,” he was referring to the same day long recognized as belonging to the Lord-the seventh-day Sabbath. This understanding is consistent with all previous biblical usage.

The early Christians continued to observe the Sabbath after Christ’s resurrection. The book of Acts records that Paul and the apostles met for worship and teaching on the Sabbath day (Acts 13:42-44; 16:13; 17:2; 18:4). There is no record in Scripture of the apostles changing the day of worship to Sunday or calling it the “Lord’s day.” The shift from Sabbath to Sunday observance occurred gradually over centuries, influenced by tradition and Roman culture rather than by divine command. https://bibleask.org/how-and-when-the-sabbath-was-changed/

The Sabbath in the New Earth

The Sabbath will not only remain holy throughout the Christian era but will also be observed in eternity. Isaiah 66:22-23 prophesies, “‘For as the new heavens and the new earth which I will make shall remain before Me,’ says the Lord, ‘so shall your descendants and your name remain. And it shall come to pass that from one Sabbath to another, all flesh shall come to worship before Me,’ says the Lord.”

This prophecy shows that the Sabbath, established at Creation, will continue to be the day of worship in the new earth. God’s people will gather every Sabbath to honor their Creator and Redeemer forever.

The phrase “the Lord’s day” in Revelation 1:10 does not refer to Sunday, as no Scripture gives that title to the first day of the week. Instead, when we let the Bible interpret itself, we find that the “Lord’s day” can only mean the seventh-day Sabbath-the day that God blessed, sanctified, and called His own from the beginning.

Jesus, the Creator and Redeemer, declared Himself Lord of the Sabbath, confirming its authority and significance for all believers. The Sabbath remains a symbol of God’s creative power, redemptive love, and promise of eternal rest. It is a day of communion with the Lord, reminding us that He alone is the source of life and salvation.
