ROMANS 8:32

the following is an excerpt from Future Grace by John Piper. may it fill your heart with hope, as it has filled mine. :>

God desired two things: not to see his Son made a mockery by sinners; and not to see his people denied infinite future grace. Surely it is more likely that he will spare his Son than that he will spare us. But no. He did not spare his Son. And therefore it is impossible that he should spare us the promise for which the Son died - he will freely with him give us all things.
...
The great promise of future grace, guaranteed in the logic of Romans 8:32, is that nothing will ever enter your experience as God's child that, by God's sovereign grace, will not turn out to be a benefit to you. This is what it means for God to be God, and for God to be for you, and for God to freely give you all things with Christ.

He who did not spare His own Son,
but delivered Him up for us all,
how will He not also with Him freely give us all things?
