If my people had heard me: if Israel had walked in my ways:

“"If My people would have heard Me, if Israel would have walked in My ways" [Psalm 81:13]. For perchance that Israel says, Behold I sin, it is manifest, I go after the affections of my own heart: but what can I do? The devil does this. Demons do this. What is the devil? Who are the demons? Certainly your enemies. "Unto nothing all their enemies I would have brought down; and on them that oppress them I would have sent forth My hand" [Psalm 81:14]. But now what have they to do to complain of enemies? Themselves have become the worse enemies. For how? What follows? Of enemies ye complain, yourselves, what are you?”

“The haters of the Lord should have submitted themselves unto him,.... Or, "lied unto him" (h); feignedly submitted to him, flattered him, pretended friendship to him, and entered into a league with him; either Israel, mentioned Psa 81:13, our God, whom and whose worship and people they hated; as every natural man is an hater of God, and all that is good, and enmity itself unto him; but these shall all submit to Christ, sooner or later, in one way or another, and acknowledge him Lord, and that he is superior to them, and themselves not a match for him; as Julian the emperor when wounded, said, Thou hast overcome me, O Galilean: but their time should have endured for ever; which Jarchi and Aben Ezra interpret of the calamities and vengeance that should come upon the haters of God, who will be punished with everlasting destruction; their worm will never die, nor their fire be quenched; it is everlasting, and the smoke of their torment will ascend for ever and ever; in which sense the word is used, Isa 13:22 or rather this is to be understood of the time, or happy state and condition, of the Israelites, which would have been of long continuance, had they hearkened to the Lord, and walked in his ways; particularly, they would have long enjoyed the land of Canaan, which was given to Abraham and his seed for an everlasting possession, and which they held by the tenure of their obedience, Gen 17:8, and so all truly gracious souls, that hearken to the voice of Christ, and walk in his ways, are in a happy state, which will endure for ever; they are blessed with all spiritual blessings, and those are for ever; the heavenly land of Canaan they shall dwell in for ever; their mansions or habitations in Christ's Father's house are everlasting; their house, not made with hands, is eternal in the heavens; their estate, possession, and inheritance is an eternal one; it is incorruptible, and fades not away; their being with Christ is for ever; and their happiness is often expressed by eternal life and eternal glory.
