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 its history; background or accomplishments. It is not based on the natural wealth, resources, economic prosperity, population, military strength, the capacity of its industry or agriculture, education system, health services, the system of governance or its leaders.
