Terry, the only answers I have heard for this were the usual.
Acts 1
6 Then they gathered around him and asked him, “Lord, are you at this time going to restore the kingdom to Israel?”
John 21
22 Jesus answered, “If I want him to remain alive until I return, what is that to you? You must follow me.” 23 Because of this, the rumor spread among the believers that this disciple would not die. But Jesus did not say that he would not die; he only said, “If I want him to remain alive until I return, what is that to you?”
2 Samuel 7
1 After the king was settled in his palace and the LORD had given him rest from all his enemies around him, 2 he said to Nathan the prophet, “Here I am, living in a house of cedar, while the ark of God remains in a tent.”
3 Nathan replied to the king, “Whatever you have in mind, go ahead and do it, for the LORD is with you.”
4 But that night the word of the LORD came to Nathan, saying:
5 “Go and tell my servant David, ‘This is what the LORD says: Are you the one to build me a house to dwell in?
12 When your days are over and you rest with your ancestors, I will raise up your offspring to succeed you, your own flesh and blood, and I will establish his kingdom. 13 He is the one who will build a house for my Name, and I will establish the throne of his kingdom forever.
These accounts don't even come close to being prophesy, yet one has to ask, is the Bible guilty of revisionism, just like the Watchtower for its failed expectations?
