The greatest failure in the world is not a lack of finance, although that is often a major problem. Other important issues can be a lack of adequate housing or being hungry at mealtimes. Sometimes there is even a lack of sufficient medical facilities or proper medical treatment. However, it can never be as big or near as important as the greatest failure that can happen to any human being. The biggest problem is not directly associated with our flesh or even our soul. The greatest problem is an eternal problem, of the spirit, of a person. This problem is a failure to know about or accept Jesus Christ as a personal Lord and Saviour. This is a problem of unbelief which effects the eternal life of all who don't believe in God and His word.
