"For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow." (Ecclesiastes 1:18).
The Knowledge of whole universe cannot save a man, but a person who increasth His Knowledge increase the sorrow or burden.
A person who have done PhD etc or more educated will not believe, if you say Him, Lord Jesus Christ raised from dead, the reason behind his unbelief is His knowledge, because He has been taught that a man couldn't be raise if he died. They are taught that the bodily started to melt in dust etc. And this person will ask so many questions, how a human being can be raised from dead and etc, etc.
But if you will go to a illiterate person and say to Him, Lord Jesus Christ raised from dead, He would believe because, He is not taught, He is innocent like the first couple, who was in Adan, their faith was perfect, they were as much innocent that they were naked but didnot care about it, they were like the Child, who only know that is to follow the given commandment, even todays age, if you will give instruction to a child not to do that, he would not do that until, he again taught or can see anyone to do like the same.
The meaning of whole is, a knowledge cannot save a man, but the faith and unquestioning following the Commandment of God.
God Bless Us everyone.amen
