It indicates that He will provide language and be a source of hope for those who had none, specifically for the Gentiles, as the Apostle Paul points out in his letter: "Wherefore remember ye also, that ye who were sometimes Gentiles in the flesh, verbally uncircumcised from the circumcision of the flesh, which was made with hands, because ye were in the time without Christ, alienated from Israel, and alienated from the covenant of promise, having no hope, and godless in the world: but now of Christ Jesus ye who were sometimes far off, are near by the blood of Christ" (Eph. 2:11-18). Even though they may have been without hope, worshipping mere creations, they were nonetheless called through faith to a knowledge of Christ, finding guidance under His care and coming to have the one who is truly and naturally God, entering into communion with the hope of the saints.
It is said there shall come His rest, His glory. This can be understood in a dual manner. For those who wish to interpret "rest" in this context as referring to the death of Christ in the flesh—which He voluntarily endured for our sake—it can be seen as granting a brief respite to His body, thus rendering death a form of honor. The Savior, our Lord Jesus Christ, is glorified for having taken upon Himself the sacrifice for humanity, willingly facing death for the sake of all lives. He expressed this truth to the heavenly Father when preparing to face the honorable cross: "Father, glorify Thy Son, that Thy Son also may glorify Thee" (John 17:1). Additionally, "Now is the Son of man glorified, and God is glorified concerning Him" (John 13:31).
The misguided actions of those who condemned Him, their malice and cruelty, turned His suffering into paradoxical glory, as they believed He was suffering against His will. Yet, through His resurrection, He conquered hell, demonstrating His dominion over death, thereby bringing forth honor and glory through His actions. Hence, it speaks of His rest and honor in this manner.
Should anyone contemplate differently regarding these reflections, they might grasp this idea: Christ will not merely serve as a beacon of hope for the Gentiles, but at a certain moment He will rise, not only to claim them but also to grant them rest infused with honor. The hearts of the saints are a gracious abode for Him, where He resides, resting within the holy souls who revere Him. To those who receive such a blessing, He becomes both honor and glory, for what can surpass the glory of having God present and living within their hearts? Thus, even now, as we earnestly seek Him, His rest in us brings honor. For "if any man hearken to my words," He says, "my Father will love him, and unto him we will come and make our abode with him" (John 14:23).
