The gospel means, the good news. But it is more than a good news! It is the good news about Salvation in Jesus Christ, the Savior of mankind.
Gospel is not just a word which proclaims about the salvation offered through Christ Jesus, but it is the “power” of God (Rom. 1:16). Why is it a power of God? Because it has the capacity to change one’s life, because it shows the power of God at work!
