Preaching the gospel is also called sharing the good news or witnessing. “To witness” is a command the Lord Jesus Christ has given to all his followers and the church. There’s no other option. It is God given duty that must be done. Paul had this to say about preaching the good news “Woe to me if I do not preach this gospel”
A nation’s greatness is not dependent on it’s history; background or accomplishments. It is not based on the natural wealth, resources, economic prosperity, population, military strength, the capacity of it’s industry or agriculture, education system, health services, system of governance or it’s leaders.
