What if the man might take the fruit from the tree of life, would eat that fruit and will live forever?
It is not about a Devil’s Delusion but about man's delusion and human escape from his own responsible choices.
To seek wisdom the Holy Scriptures are the best source for getting to know everything man has to know to make the best of his life and to see what is going to happen in this world, so that man can protect himself for the horrible war to come. Man should know that every writing inspired by the Most High Elohim Hashem Jehovah is profitable for teaching, for reproof, for correction, and for instruction which is in righteousness, that the man of God may be complete, thoroughly equipped for every good work and may find the Way to God and to the small gate of the Kingdom of God.
in this world where not many are interested in God it is better that we make sure more people come to know that it is best to get to know what is written in those very old writings which form the Bible.
