What was the sign Calvinists believed God would send them to indicater they were in divine favor and destined for salvation?

Calvinists believed that signs of divine favor and predestination to salvation could be indicated by a person's moral behavior, success in life, and a sense of inner assurance or conviction of faith. They emphasized the concept of "the elect," suggesting that those who exhibited a pious lifestyle, prosperity, and a strong personal faith were likely among the chosen ones for salvation. This belief led to a strong work ethic and a focus on living a disciplined, virtuous life.
