The disciples expected that Christ would "come" as King, with a royal presence, and to remove the Romans and thrown down the corrupt temple, all at the same time and soon! It was a disappointment for them it turned not out that way, but they came to understand we could have an even much better future because of what Jesus had done. Though they also became convinced of the necessity to be prepared for the time that Jesus would return and that each believer could add by his effort of preaching, to bring the time closer.
2000 years ago Jesus spoke about such teachers who think they are the only ones who can explain the Bible. Today people should be aware that it is the Scriptures itself that can explain everything and that it is Jeshua, Jesus Christ, whom we should follow as the most perfect teacher.
In the word there are many words going around, which makes us to decide which words we want to follow. There is the need to believe in the Maker of all things haven given His Word to mankind and considering it the truth. when the divine Maker is not a verity His word also can not be a reality and a truth. we look at the exclusive god between the many gods and how His word by coming from the Highest of all His Words should also be recognised as from the Highest and pure.
