About Satan.

Can someone explain this. I just wanted to know...

According to Genesis 3:14

And the LORD God said unto the serpent, Because thou hast done this, thou art cursed above all cattle, and above every beast of the field; upon thy belly shalt thou go, and dust shalt thou eat all the days of thy life

OK, most Christians believed that the serpent in the Genesis narrative is Satan (also see Rev. 20:2). 

Now according to the story, God cursed Satan above all cattle, and above every beast of the field - wait? Cattle? Every beast of the field? I thought Satan was an angel so why the issue with cattle and field animals?

Upon thy belly shalt thou go - So god cursed Satan to crawl on his belly, yet we find Satan on Job 1:6-8 "going to and fro on the earth, and from walking up and down on it." I though he shall be crawling on his belly forever?

We also find Satan in Matthew 4:1-10 tempting Jesus and bringing him "up into the holy city, and set him on a pinnacle of the temple," and "into an exceedingly high mountain" He did all that while crawling in his belly? 

Going back to Job, here's someone that was already cursed by god yet all of a sudden this Satan can just enter god's domain and talk to god as if nothing happened? And take note, he (Satan) even came along together with the sons of God. 

Weird.

Additional question - How can angels sin?

According to 2Peter 2:4  For if God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment; 

Now, angels are heavenly beings - living in heaven (a perfect place according to Christian belief - the abode of God, the invisible realm of holiness and happiness). According to the International Standard Bible Encyclopedia, angels are the holiest of created beings.  Intelligent holy beings who are instruments of the Divine will. They also interprets god's will. God called them as "holy ones" (Job 15:15 ) even though he do not trust them." As Job 15:15 says, "Behold, he puts no trust in his holy ones; yea, the heavens are not clean in his sight." Now, holy means morally and spiritually excellent.  Yet they sinned? And god cannot even trust these "holy ones?" 

Why is this "perfect" god (whose work is always perfect according to Deuteronomy 32:4 ) always flunk when trying to create morally and spiritually excellent beings? Free-will? So angels have free-will? Now, if angels came first before humans, and this god already know that "free-will" can corrupt his creations, why apply free-will to humans (his favorite pets)? He already seen how free-will corrupted his "perfectly created, intelligent holy beings" to the point that he can't even trust them diba?

Tanga lang ba talaga?
