“And they shall no more be a prey to the heathen, neither shall the beast of the land devour them; but they shall dwell safely, and none shall make them afraid.” Ezekiel 34:28 (KJB)
These verses (chapter 34:20-31) are of a time when King David will become the Prince alongside the King of kings in the City of Jerusalem. Let me share with you the thoughts of Matthew Henry from his commentary of the whole Bible. It will give us some application for the Christian of any time or day.
“That they shall enjoy a holy security under the divine protection. Christ, our good Shepherd, has caused the evil beasts to cease out of the land (Eze_34:25), having vanquished all our spiritual enemies, broken their power, and triumphed over them; the roaring lion is not a roaring devouring lion to them; they shall no more be a prey to the heathen nor the heathen a terror to them, neither shall the beasts of the land devour them. Sin and Satan, death and hell, are conquered. And then they shall dwell safely, not only in the folds, but in the fields, in the wilderness, in the woods, where the beasts of prey are; they shall not only dwell there, but they shall sleep there, which denotes not only that the beasts being made to cease there shall be no danger, but, their consciences being purified and pacified, they shall be in no apprehension of danger; not only safe from evil, but quiet from the fear of evil. Note, Those may lay down and sleep securely, sleep at ease, that have Christ for their prince; for he will be their protector, and make them to dwell in safety. None shall hurt them, nay, none shall make them afraid. If God be for us, who can be against us? Therefore will not we fear, though the earth be removed. Through Christ, God delivers his people not only from the things they have reason to fear, but from their fear even of death itself, from all that fear that has torment. This safety from evil is promised (Eze_34:27): They shall be safe in their land, in no danger of being invaded and enslaved, though their great plenty be a temptation to their neighbours to desire their land; and that which shall make them think themselves safe is their confidence in the wisdom, power, and goodness of God: They shall know that I am the Lord. All our disquieting fears arise from our ignorance of God and mistakes concerning him. Their experience of his particular care concerning them encourages their confidence in him: “I have broken the bands of their yoke, with which they have been brought and held down under oppression, and have delivered them out of the hand of those that served themselves of them, whence they shall argue, He that has delivered does and will, therefore will we dwell safely.” This is explained, and applied to our gospel-state, Luk_1:74. That we, being delivered out of the hand of our enemies, might serve him without fear, as those may do that serve him in faith.” Matthew Henry Commentary
The only hope for your personal peace is to be at peace with God. There is only one way to be at peace with Him, and that is through His gift to you. That is His Son Jesus Christ and His sacrifice on the cross, His burial, and resurrection. Believe Him, repenting of your sin, and you will have peace with God.
