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.
In Scriptures people are asked to teach their children diligently and to go out to tell everybody and to reason about the importance of faith in Christ, Jeshua or Jesus Christ being the sent one from and son of God bringing people to God and to salvation..
Peter evidently did not view himself as the rock on which Jesus would build his congregation, since he wrote at 1Pe 2:4-8 that Jesus was the long-foretold “foundation cornerstone,” chosen by God himself. Similarly, the apostle Paul referred to Jesus as the “foundation” and “the spiritual rock.” (1Co 3:11; 10:4). For every Christian or follower of Christ their church or community should have Jesus as their cornerstone and not as such one or another hierarchical religious organisation.
Before calling a church or religious group a "cult" or "sect" one should seriously examine and clarify what one means with those qualifications.
In this godless world we all should remember that man shall not live by bread alone, but by every word going forth through the mouth of God Which He has provided for the whole world in many Bible translations. Nobody may forget that in whatever language the Bible is inspired by God and as such protected by God's Power so that it can be useful for every person on earth for teaching, for reproof, for correction, and for training in righteousness, in such a way that the person dedicated to God may be capable and equipped for every good work.
KJV-only people often forget that in the many Bible Translation committees, all over the world, can be found many serious honest people who like to do justice to the Word of God. Several brainstormers from all sorts of religious groups often work together as a team to sit down to do some good bible hermeneutics for getting the best contemporary words placed in good readable and understandable phrases.
