Final answer:
Calvinist theology indeed emphasizes God's sovereignty and includes the doctrine of predestination, meaning that a person's salvation is predetermined at birth, which is true.
Step-by-step explanation:
Calvinist theology certainly emphasizes the sovereignty of God in the dynamics of grace and salvation. This is evident through the doctrine of predestination, which is a foundational element in Calvinist thought. According to predestination, God has foreordained all events, including the eternal destiny of every human soul. Thus, a person was saved from the time of their birth, and nothing done in life could change this predetermined fate. This leads us to the true answer for the initial question, that according to Calvinist theology and the doctrine of predestination, a person was saved from the time of his birth, which is True.
In Geneva, John Calvin established a community that strictly adhered to these principles, often leading its members to look for signs in their daily lives that might indicate whether they were among the elect. The Puritan work ethic was also influenced by this doctrine, as hard work and success in life were often seen as signs of election.
