What does the Bible say about the Sabbath rest?

In the Scriptures, particularly in Matthew 11:28-29 and Hebrews 4:9-11, we see that Christ embodies the true rest for God's people. The Sabbath was a picture of the ultimate rest that believers find in Jesus, who offers rest from the labor of trying to earn righteousness through the law. Instead, through faith in Christ, we enter into the gospel rest where our works do not justify us, but His work does. He invites those who are weary to come to Him for that rest, illustrating that true peace and rest are found not in observing a day but in a relationship with Him.
