" For I am not ashamed of the gospel of Christ, for it is the power of God to salvation for everyone who believes, for the Jew first and also for the Greek."
The Origin of the gospel: It is the gospel of Christ
The Operation of the gospel : It is the power of God
The Outcome of the gospel: It is the power of God unto salvation
The Outreach of the gospel: to everyone who believes.
" go into all the world and preach the gospel to every creature." was Christ commission. And it has never change. That is why people continue to go to places that need the gospel. God does not ask people to behave in order to be saved, but to believe.
" For whoever calls on the name of the Lord shall be saved."-Romans 10:13
It is still true today.
