Charles H. Spurgeon on Psalms 80:18

So will not we, etc. How are we to understand the connection between this and the preceding words? It may be understood two ways.

1. As it would oblige them to the yielding of steadfast obedience; it would lay them under a special engagement never to revolt any more, as they had done; if God would grant this request, it would be a most eminent tie and bond upon them to the most constant and faithful service.

2. As it would enable them to yield such obedience. And this I conceive to be chiefly aimed at; if God would lay such help upon Christ for them, they should receive power by that means to discharge their duty to him better than ever heretofore; though they were very feeble and wavering, false and treacherous of themselves, yet here would be a successful remedy. Timothy Cruso.
