A.T. Robertson Commentary Romans 8:32

"He that spared not his own Son, but delivered him up for us all, how shall he not also with him freely give us all things?" — Romans 8:32 (ASV)

He that (ος γε). "Who as much as this" (γε here magnifying the deed, intensive particle).

Spared not (ουκ εφεισατο). First aorist middle of φειδομα, old verb used about the offering of Isaac in Ge 22:16. See Ac 20:29.

Also with him (κα συν αυτω). The gift of "his own son" is the promise and the pledge of the all things for good of verse 28. Christ is all and carries all with him.
