Original sin would be a doctrinal view that all are "by nature the children of wrath" and go astray from the womb (Ephesians 2:3, Psalm 58:3, Isaiah 53:6).
A different view was expressed by Don Richardson in his book, Heaven Wins: Heaven, Hell and the Hope of Every Person, Regal publisher, 2013, which I read a few weeks ago. If I understand it correctly, Don's book asserts that a "salvific" gospel message is proclaimed by natural revelation (nature and astronomy) even if it is proclaimed in a fuller and richer way by the Bible itself. God is glorified that Christ's Redemptive work is more than a "Pyrrhic" victory on behalf of just an exclusive few but that Christ's Redemption is more inclusive and saves people more widely than what many Christians imagine.
He quotes Psalm 97:6 and Acts 14:17 and Romans 1:20:
- The heavens proclaim His Righteousness. All peoples (every nation) see His Glory.
- He [Theos - God] left not himself without witness, in that He did good and gave us rain from heaven and fruitful seasons, filling our hearts with food and gladness.
- Since the creation of the world God's invisible qualities-his eternal power and divine nature have been clearly seen [not just dimly sensed] being understood from what has been made.
The universe is observable across length, width, height and time and God is Omnipresent in these. But, the universe also includes intellect, emotion and will and when these are acknowledged in same fullness we have the attributes of Omniscience, Omnisentience and Omnipotence which define God. In the three persons of the Trinity, we see three, coordinated manifestations of Infinite Intellect, Infinite Emotion and Infinite Will.
"Heaven Wins" also asserts an "age of accountability" regarding infants who die in infancy.
Many strong Christians have held to an "age of accountability". I have been more influenced by the doctrine of original sin.
IMHO, God's intellect, emotion and will are seen in Intelligent Design and God's Providential interventions in history. Regarding Providence, I would describe the British escape from Dunkirk during WWII as one cited example.
