Suppose the following line of characters represents the entirety of God’s creation:
fasdfhioehnfreiowoiewjfioaewjnfidnscndsiofiaosjefienfiaewnfiendnsfiwnfiewnfiwnfiew
In non-Universalist thought God saves only:
fasdfhioehnfreiowoiewjfioaewjnfidnscndsiofiaosjef
Or maybe only:
fasdfhioehnfr
Or even perhaps:
fa
I think it a denial of the doctrine of God the Savior to say that He does not save His entire creation, even as it would be a denial of the doctrine of God the Creator if one were to say that there were some things that God didn’t create. Saying, “God will save Jim, but He won’t save Mike” is just as nonsensical as saying, “God created birds, but He didn’t create butterflies.”
Only Universalism recognizes that God is the Savior (with a capital “S”) instead of a mere savior who manages to save some but not all. God created and will save everything. Any other position effectively denies that God is the Creator and the Savior.
