Isaiah 46:4

“And even to your old age I am he, &c.] The same he ever was, the eternal and unchangeable Jehovah; the same in his love and affections; in his sympathy and care; in his power and protection; in his promises, truth, and faithfulness to his people, in their last days, as at the first moment of their conversion; and therefore they are safe; (see <19A227>Psalm 102:27 <390306> Malachi 3:6): and even to hoar hairs will I carry youf911; which is doing more than the most tender parent does, or can, or need to do!

In this the care of God for his people surpasses that of the most tender parent, and the most kind nourisher of the young.

But not so with God. His people are always the objects of his tender solicitude. Age does not make them less dependent, and experience only teaches them more and more their need of his sustaining grace. The argument here…”
