In the book A Saviour for All Seasons, William Barker tells about a bishop who once stayed at the home of a college president who also served as professor of physics and chemistry. The bishop expressed his belief that just about everything in nature had been discovered and all inventions had already been conceived.
His host politely disagreed and said that he felt that there would be many more discoveries. The bishop got angry and challenged the professor to name one such invention. He replied that he was certain that within 50 years people would be able to fly.
“Nonsense!” sputtered the outraged bishop. “Only angels are intended to fly.”
The bishop’s name was Wright, and he had two boys at home who would prove to have greater vision than their father. Their names: Orville and Wilbur.
“Where there is no vision, the people perish…”—Proverbs 29:18.
Jesustrek 
People get stuck in the now or yesterday and forget about the tomorrow or the next day. I think this is especially true when it comes to the promises God has made us.
