A restatement of a text, passage, or work giving the meaning in
You could not really call your 'paraphrased' sentence a paraphrase as it uses too much of the original form.
The key here is that you need to give the meaning 'in another form'.
You need to use different words to express the meaning.
In order to paraphrase the sentence you have quoted. First of all you have to be absolutely clear on the meaning of it yourself. Then you need to pick suitable words to express the meaning. This is actually a rather advanced skill as you need to not only fully grasp the meaning of the original sentence, but you need to have a sufficiently advanced vocabularly and written skill set, such that you can select a completely different form, to represent the original meaning.
You would usually paraphrase to make the meaning clearer for a different type of audience than the original sentence was intended for ; or to summarise a lengthy series of statements into a shorter more succinct form for brevity in relating the meaning.
Taking your phrase:
One's belief is never consummated except unless he realizes........
What does this mean?
The belief that someone has, is never made complete unless he realizes...
I fear you may have ended the original sentence too early, because as it stands it is not crystal clear what the intended meaning of that sentence was. The meaning depends on what the realization is, that the person needs to have.
However in its present form, you might paraphrase it as follows: -
Someone never truly believes until he realizes that...
