This might also be called the parable of the harvest. Until the harvest, the sower does not see how well the seed has grown. The parable has some similarities with that of the Sower. In 4 :20 there is a quotation from Joel 3: 13 which describes God's final Judgement Day. It will not be until the end of the present age and the final Judgement that all of those who have entered God's Kingdom will be known.
