Called chosen. (Acts 20 v31)

 Matthew 22 v14 reads,'Many are called ,but few are chosen', Who does the calling?,all of us who know the Lord ,to some degree, how otherwise would people hear about Jesus and be saved,as Paul puts it,how can they hear about Him unless someone tells them(.Romans 10 v 14) You may think leave it to the professionals,not so that is a cop out,we all have a responsibility to witness to others.I  personally get frustrated that those who are ministers and are neglecting to proclaim the gospel.They rarely mention sin or speak of hell ,it's as if they are afraid of offending people,but in doing that they are offending God. Many are hearing the gospel now  through the internet,in the town where I live I saw a team of people witnessing in our town center, that encouraged me.The call of the gospel  goes out to many but our Lord says ,'few are chosen'.some people may struggle  with what Jesus said,but if Jesus said it then it's true we must accept that in the end salvation is a work of God,we must see that in it's fullness ,our responsibility is to be faithful in whatever way we can by telling  people about Jesus.
