Explain one strength of John Calvin's predestination.

One strength of John Calvin's predestination is that it provides a sense of security and assurance to believers. Calvin's doctrine of predestination states that God has predetermined who will be saved and who will be damned, and that nothing a person does can change this. This means that believers can have confidence that their salvation is secure, regardless of their actions. This assurance can be comforting to believers, as it removes the burden of having to constantly worry about their salvation.
