If we’re all “beautiful” in the sight of the Lord, then why is He so selective and prejudicial with regard to the handicapped?

Leviticus 21:18. This rule had nothing to do with individual rights. Serving as a priest was not a right but a privilege reserved for only a few. Those with physical defects were no more discriminated against than were most of the people of Israel: Only men of a certain age, ceremonially clean, without defect, from the tribe of Levi and descended from Aaron were granted the privilege to represent God as priests. At issue was whether the priests would project an image of a holy, perfect God to the people. Like the sacrifices that had to be without defect, the priests were to typify Christ’s perfection (Heb 9:13-14). The uniqueness of the call preserved the image. Nonetheless, Aaron’s descendants with defects were not barred from other priestly benefits.
