As we keep saying: GOD is God and He can do whatever He wants; what He does is ALWAYS perfect; and He always has His reasons for doing the things He does. Since God is holy and perfect, He cannot be around imperfection. He cannot be around sin of any kind.
We simply cannot comprehend God with our limited human mindsets. But, from the beginning He told us that He requires perfection in His Presence. He plainly told us that the offerings we present MUST be WITHOUT blemish. Therefore, it stands to reason that people with any kind of defect cannot approach the altar. It's an act of amazing grace that ANY man is allowed near His altar at all, because we are sin-filled by nature (thanks to Adam and Eve!
