Matthew Poole and continuators on Hebrews 4:9

9 There remaineth therefore a rest to the people of God .

Here the Spirit concludes from his former Proofs, That there is a more excellent Rest revealed to Faith in the Gospel, which is remaining, future, and to come, and will sure, and most certainly do so; tho it be behind, yet it will be enjoyed. A Sabbatism, which is a State and Season a of most glorious Rest, see v. 10. shall be enjoyed by sincere Believers, the true Israel of God, of whom he is the Proprietor, and who are for their eternal State so excellently holy, and of so divine a Nature, that he is not ashamed to be called their God. They have an Entrance here into the initials of this Sabbatism in internal Peace, and the glorious Liberty of the Children of God; and by it secured of their full Possession of it in the eternal Inheritance of the Saints in Light. Colos. 1.12, 13. 1 Pet. 1.3, 4, 5. Rev. 14.13.
