Jesus invites the burdened to come to Him.
The rest Jesus gives is not the absence of work but the presence of a gentle Master.
What the Scriptures say
Come unto me, all ye that labour and are heavy laden, and I will give you rest. Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls. For my yoke is easy, and my burden is light. Matthew 11:28-30 · KJV
He maketh me to lie down in green pastures: he leadeth me beside the still waters. Psalms 23:2 · KJV
But they that wait upon the LORD shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint. Isaiah 40:31 · KJV
