Genesis 18:12 Therefore Sarah laughed within herself, saying, After I am waxed old shall I have pleasure, my lord being old also? 13 And the Lord said unto Abraham, Wherefore did Sarah laugh, saying, Shall I of a surety bear a child, which am old?
That question as to the whereabouts of Sarah, by the strangers had breached cultural norms, for back in those days, strangers were not supposed to know a man’s wife by her first name. So, when this had occurred, Abraham knew that he had inadvertently invited angels and one member of the God-head into his home. Therefore, the answer to our first question: Are we alone? Is No, we have never been alone.
Thus, the very next question we will need to address is: Can the evil angels do all of those things previously mentioned, which Holy angels have the capability of doing? The answer is: Absolutely!
[D.A pp 129] Placing Jesus upon a high mountain, Satan caused the kingdoms of the world, in all their glory, to pass in panoramic view before Him. The sunlight lay on temple cities, marble palaces, fertile fields, and fruit-laden vineyards. The traces of evil were hidden. The eyes of Jesus, so lately greeted by gloom and desolation, now gazed upon a scene of unsurpassed loveliness and prosperity.
Matthew 4:9 And he saith unto him, All these things will I give thee, if thou wilt fall down and worship me.
May The Lord add His blessing to the study of His word. God bless!
