The Medrash Yalkut Shemoni (click here) brings Chazal's words: Who ever turns himself away from aveira (sin), then even if he is a Israelite, he is worthy of bringing a sacrifice on the alter like the Kohen Gadol"... "And who ever makes himself lazy from sin and doesn't sin, merits to enjoy the shine of the Shechina like the ministering angels".
