Psalm 18:19 (ESV) … “He brought me out into a broad place; he rescued me, because he delighted in me.”
Ver. 19. He brought me forth also into a large place, &c.] Into heaven, a place of the glorious liberty of Christ, after his captivity to death and the grave, whither he ascended leading captivity captive, and of the children of God; and a spacious place, where there is room enough for Christ and all his people; here he now is, and will remain till his second coming, and from hence we expect him; see John 14:2, 3. Compare with this Psalm 31:8 and 118:5.
He delivered me, because he delighted in me; God delivered David from all his enemies, because he was a man after his own heart, in whom he delighted; not for any merit and worthiness in him, but of his good will and pleasure: he delivered Christ because he was his elect, in whom his soul delighted; and who was daily his delight, rejoicing in his presence before the world was: and he delivers his church and people, because they are his (Hephzi-bah “my delight is in her”), in whom is his delight; the Father delighted in them, and therefore chose them to salvation; the Son delighted in them, and gave himself for them, and ransomed them out of the hands of him that is stronger than they; the Holy Spirit delighted in them, and therefore regenerates, renews, and sanctifies them, and seals them up unto the day of redemption.
