We study a canonical, reduced phase space quantization of the at Friedmann- Robertson-Walker universe which is formulated as a gauge invariant fashion in the classical theory. We construct a wave packet as the wave function of the universe and compute the expectation value of the scale factor. As a results, it is shown that the initial singularity of the universe is avoided in our models.
