This is identical to Mark 10:15 although the KJV translations are slightly different.  The Greek word translated as "receive" has a clear double meaning.

  The "verily" phrase is used frequently by Christ as a personal signature. Its vocabulary and meaning are discussed in detail in this article. Currently, "honestly, I'm telling you" is the translation I currently use. Christ has fun with his frequent use of this phrase. The word translated is as "verily" is an exclamation that means "truly" or "of a truth." It is an untranslated Aramaic word that is echoed by a similar Greek word, and a good piece of evidence that Christ taught in Greek, not Aramaic.

The word translated as "verily" is the Hebrew word that means "truly" or "certainly," but it sounds like the Greek word with the same meaning. In Greek, the word also means "to reap."

The word translated as "I tell" is the most common word that means "to say," and "to speak," but it also means "to teach," which seems to be the way Christ uses it more frequently. It also has many ancillary meanings such as "to count" ("to number" or like we might say, "to recount" a story) or "to choose for yourself." Christ usually uses this word to refer to his own speaking or teaching.

The Greek pronoun "you" here is plural and in the form of an indirect object, "to you", "for you", etc. 

The word translated as "whosoever" is a demonstrative pronoun ("this" "that"), but it often acts as a pronoun ("the one that), especially a connective pronoun ("the one that") introducing a dependent clause.

"Shall" is a particle used with verbs to indicate that the action is limited by circumstances or defined by conditions. There is no exact equivalent in English, but it is translated as "would have", "might", "should," and "could."

The negative "not" used here is the Greek negative of a subjective opinion. The sense is that "you don't want" to do something, not that it isn't done or don't think something that might be true. If it wasn't done or wasn't true, the objective negative of fact would be used.

"Receive" can be two different Greek terms.  The Greek verb that the KJV prefers means "welcome" when applied to people and "take" or "accept" when applied to things. But it could also be another Greek verb that "bring to light" and "exhibit". In both cases, it is not the future tense, but a form that indicates a possibility at some point in time.

The word translated as "kingdom" can be the region, the reign, the castle or the authority of a ruler. Christ does not seem to use it to mean a physical region, so its translation as "reign" or "realm" seems more appropriate. This is especially true because the "reign" of a king means the execution of his will. This concept as "the kingdom of heaven" is discussed in more detail in this article.

The word translated as "God" means "God" and "deity." It is introduced with an article, so "the God" or "the Divine".  Christ often uses it this way perhaps to indicate the one God as opposed to the pagan gods. This is an example of the near parallel "kingdom of heaven" in Matthew 18:3 is turned into the "kingdom of God" here.

The word translated as "as" has a very broad meaning, translating as "how", "when", "where", "just as", "like," and related words.

The Greek word translated as "a little child" means "little child" and refers to children younger than seven. It is one of several words Jesus uses to refer to children, see this article.

"Ye shall enter" is a word that means "go or come into" and has the double meaning of "coming into one's mind."  The "shall" does not indicate the future tense. The form of the verb is the form of possibility that can happen at any time, past, present, or future.

The "in no wise" here is both of the Greek negatives used together. Greek has two negatives, one objective, one subjective. The use of both together is more extreme, like saying "you cannot really think."

"Therein" is two Greek words meaning "into it". The word translated as "--in" means "into" a place, "towards" as a direction, "in regards to" a subject, and "up to" limits in time and measure. The word translated as "there" is the Greek word commonly translated as pronouns in English.  Its form matches the Greek "kingdom".
