How do we know that salvation is a command?

In Matthew 11:28, Jesus commands, 'Come unto me, all ye that labor and are heavy laden, and I will give you rest.' This command illustrates that Christ's call to salvation is not merely an invitation but involves a directive from God that carries the weight of authority. When God commands individuals to believe, it indicates an expectation of obedience. Ignoring this command leads to condemnation, as disobeying God incurs the death penalty for sin. Salvation as a command emphasizes its necessity and urgency in the context of human sinfulness and the need for divine intervention.
