What does it mean that salvation is by command, not invitation?

The idea that salvation is by command rather than mere invitation underscores the authority and sovereignty of God in the salvation process. The preacher emphasizes that when Christ calls sinners, it is a command to follow Him, rather than a polite invitation that can be accepted or declined at will. This concept is illustrated in the call of Matthew, which represents God's sovereign choice and initiative in reaching out to individuals. The command of God assures us that His chosen will respond positively and come to faith in Christ, as seen in John 6:37, where Jesus declares that all that the Father gives Him will come to Him. This further illustrates that salvation is fundamentally rooted in God's will and purpose.
