And right up to old age I, [Yahweh], am the same And right up to grey hair I will myself shoulder the weight.
It is I who made,
and it is I who will carry,
and it is I who will shoulder the weight -
(Isaiah 46:4, translation by Alec Motyer)
I don't know about you, but I need to hear over and over again that it is God that shoulders the weights, it is he who carries the burdens. And this is all of his rich and glorious grace, and because this is of God's grace, it will last forever. "Our position on his burden-bearing shoulders is totally down to him." (Motyer)
It is this that becomes the source of the kind of singing we belt out in How Firm A Foundation, by Richard Keen:
The soul that on Jesus has leaned for repose,
He will not, he cannot desert to its foes.
That soul, though all hell should endeavor to shake,
He'll never, no never, no never forsake!
Accepting, and reveling, in this is Growing in Grace.
