And how!

"The proselyte who associates himself voluntarily with Israel won high praise from the rabbis

The ger is dearer to G-d than Israel was when the nation assembled at the foot of Mount Sinai. For Israel would not have accepted the Torah without seeing the thunders and the lightning and the quaking mountain and hearing the sound of the shofar, whearas the proselyte, without a single miracle, consecrates himself to the Holy One, praised be He, and puts upon himself the yoke of the Kingdom of Heaven. Can anyone be deemed more worthy of G-d's love?" (Conversion to Judaism: A History and Analysis, 59-60)
