What does 'Many are called but few are chosen' mean?

* It is not just for Pastors, But also for those answer the call to salvation but don't walk in it. * All people have the opportunity to believe but few choose to respond to the invitation. The phrase is used by Jesus as a summary of the Parable of the Wedding Feast and is best understood in this context. It refers to the choosing at the Judgement of those who have responded to God's call.
