Once the proletarian state possesses political power and controls the means of production, it will “wither away” over time as it suppresses the bourgeoisie and moves toward a classless society. While the state must exist while class distinctions remain, it becomes superfluous in a classless society. The use of force is no longer necessary to suppress class antagonisms, because there are no classes. Lenin includes a long quote from Engels to explain this phenomenon, a portion of which is sampled below:

As soon as there is no longer any social class to be held in subjection, as soon as class rule, and the individual struggle for existence based upon the present anarchy in production, with the collisions and excesses arising from this struggle, are removed, nothing more remains to be held in subjection — nothing necessitating a special coercive force, a state. The first act by which the state really comes forward as the representative of the whole of society — the taking possession of the means of production in the name of society — is also its last independent act as a state. State interference in social relations becomes, in one domain after another, superfluous, and then dies down of itself. The government of persons is replaced by the administration of things, and by the conduct of processes of production. The state is not ‘abolished’. It withers away. This gives the measure of the value of the phrase ‘a free people’s state’, both as to its justifiable use for a long time from an agitational point of view, and as to its ultimate scientific insufficiency; and also of the so-called anarchists’ demand that the state be abolished overnight.” (From Anti-Düring)

If you agree with the premises behind this argument, the conclusion must follow. If the state arises from class antagonisms in society and exists for the purpose of class suppression, it must therefore exist while there are classes (even during a proletarian revolution!) and start to die off once class is abolished. Engels’ description, “the government of persons is replaced by the administration of things, and by the conduct of processes of production,” explains the change in the nature of the State very well. Lenin points out that under the dictatorship of the proletariat, the State is no longer “the State” proper, but a different kind of institution altogether.
