Jesus' question here marks the conclusion to His explanation of the miracles that the disciples' question in verse 36 requested. "All these things"probably refers to everything that Jesus had said to the disciples. The disciples claimed to understand what Jesus had said, and presumably they did understand at least superficially (cf. 15:16).
"Matthew contains a total of seven parables, the first and longest of which has to do with Jesus' parabolic method. The rest of the parables have to do with the kingdom of heaven. Every one of the six stresses the hiddenness of the kingdom. It is like treasure hidden in a field, like yeast hidden in dough, like good seed hidden in soil. But we have become bottom-line conscious in the institutional Church and in parachurch organizations. We cannot raise money to support our ministries unless we can quote statistics concerning how successful we are. We have to be able to measure results. We want to evaluate the harvest day after day after day so that we can use the information in our fund-raising endeavors. And we forget that the real impact of the Church of Jesus Christ in the world is immeasurable. We will only know what it is at the harvest, which is the end of the age."572
