4. But Jesus was no mere moralist legislator offering His ward as exclusive authority. It fell to Him to complete the prophecies which had announced His advent, by means of the exceptional nature of His Spirit and His divine mission. Jesus came to teach mankind that true life is not the one lived here on Earth, but rather the life lived in Heaven. He came to show the pathway to this Kingdom, how lo be reconciled with God and to present these facts as part of things to come which would enable mankind to fulfill its destiny. However, He did not explain everything, but limited Himself to offering only the initial part of the truth on many subjects, saying that Man as yet could not understand the whole truth. But He talked about all things in implied terms. In order for people to be able to understand the hidden meaning of His words it was necessary for new ideas and knowledge to mature, so bringing the indispensable key, as these things could not appear before the human Spirit had achieved a certain degree of maturity. Science still had to play an important part in the emergence and development of these ideas; therefore it was necessary to give time for science to progress.
