"Ask, and it shall be given unto you; seek, and ye shall find; knock, and it shall be opened unto you. For every one that asketh, receiveth; and he that seeketh, findeth; and to him that knocketh, it shall be opened."
Just after the caution to not give holy things to the unworthy, Christ reminds all of their obligation to ask, seek and knock. If you will ask it will be given to you. If you seek, you will find it. If you knock, things will be opened to you. But be careful not to give what is holy to the unworthy.
These ideas are related in two ways:
First, if you want what is holy, then stop being a "dog" or a "swine." Ask, seek and knock.
Second, if you are one who is qualified and will receive holy things by your willingness to be repentant, then press forward by asking, seeking and knocking. If you do, the things which are most holy will be given.
"For every one that asketh, receiveth." Really? Everyone? Even you? That is what Christ is saying. However, the manner in which you will receive is illustrated by "The Missing Virtue" in Ten Parables. Meaning that the effort to receive what you have asked the Lord could take nearly two decades, and a great deal of internal changing before you acquire what you lack. Receiving may include not only what you've asked to receive, but also everything you do not have in order to finally qualify to receive what you seek.
What do you associate with "findeth?" Does it suggest to you active effort, or passive receipt? To "find" something you are missing (even a small thing) what must you do? If searching is required to locate, then what do you suppose the Lord is implying by the word "findeth?"
What does it mean that "it shall be opened?" Does "opening" imply merely a view? Does it suggest also 'entering in?' If it opens to view, and you then fail to 'enter in' has "opening" been worthwhile? Has anything been accomplished? Does it suggest that there is activity required of someone who has something "opened" unto them?
It is my view that the words chosen all imply a burden upon the one who asks, seeks and knocks. They are not entitled to anything just by speaking the words. They must make the effort to search into and contemplate the things they seek. Then they must change and repent of everything amiss in their lives that is revealed to them. This is to be done before they can see what is to be shown to them. If, for example, a person wants to see the other side of the mountain, they can ask daily for a view to be opened to them without ever seeing the other side. But if the Lord prompts them to take the path to the top, the Lord has given them the means to "find" and "have opened" to them the very thing they seek. Provided, of course, they are willing to walk in the path to the top of the mountain. When they remain on the valley floor, asking or demanding more, they are not really asking, seeking and knocking. They are irritating and ungrateful. The Lord's small means are capable of taking the one who seeks to the very thing they desire. (Alma 37: 7.) But without cooperation with Him they can receive nothing.
The Lord's small means are how great things are brought to pass. (1 Ne. 16: 29.) But for some people the Lord's answers are never enough. However, when the humble who ask, seek and knock follow Him in these small means, they will eventually stand in His presence and partake of eternal life. But not until they have done as all others have done before them. Faith is only replaced by knowledge when the faith is strong enough to rend the veil. At that point, there is no great advantage to the person who has already attained to this understanding by their faith. I've written about this in The Second Comforter. It is a true principle and remains true even today.
