Charles H. Spurgeon on Psalms 146:5

Happy is he that hath the God of Jacob for his help. Heaped up is his happiness. He has happiness indeed: the true and the real delight is with him. The God of Jacob is the God of the covenant, the God of wrestling prayer, the God of the tried believer; he is the only living and true God. The God of Jacob is Jehovah, who appeared unto Moses, and led the tribes of Jacob out of Egypt, and through the wilderness. Those are happy who trust him, for they shall never be ashamed or confounded. The Lord never dies, neither do his thoughts perish: his purpose of mercy, like himself, endures throughout all generations. Hallelujah! Whose hope is in the LORD his God. He is happy in help for the present and in hope for the future, who has placed all his confidence in Jehovah, who is his God by a covenant of salt. Happy is he when others are despairing! Happiest shall he be in that very hour when others are discovering the depths of agony. We have here a statement which we have personally tried and proved: resting in the Lord, we know a happiness which is beyond description, beyond comparison, beyond conception. O how blessed a thing it is to know that God is our present help, and our eternal hope. Full assurance is more than heaven in the bud, the flower has begun to open. We would not exchange with Caesar; his sceptre is a bauble, but our bliss is true treasure. In each of the two titles here given, namely, "the God of Jacob", and "Jehovah his God", there is a peculiar sweetness. Either one of them has a fountain of joy in it; but the first will not cheer us without the second. Unless Jehovah be his God no man can find confidence in the fact that he was Jacob's God. But when by faith we know the Lord to be ours, then we are "rich to all the intents of bliss."
