How do we know that salvation is a command from God?

Salvation is indicated as a command in Scripture when God calls individuals to repent and believe the gospel. Acts 1:4-8 highlights that Jesus instructed His followers to wait for the Holy Spirit, a directive underscoring the active nature of God's saving grace. Moreover, salvation is not merely an invitation but a divine command to turn towards Christ, emphasizing His authority over all creation. Throughout the New Testament, we see that belief in Jesus as Lord and Savior is mandated, as it is the only way to receive eternal life, highlighting the seriousness and urgency of God's call to salvation.
