Jesus told 8 kingdom of heaven parables from a boat. (Matthew 13 and Mark 4).
Four of these parables were field parables pointing to the fact that the kingdom consisted of "good seed" /sons of the kingdom/church that would start out small but grow to an enormous size having birds/weeds/demons/false Christian's, resting in its branches right up until the harvest.
This kingdom of heaven, has nothing to do with 1914 or any other year. It has to do with the king and his true followers.
