I have question about Genesis 18 and the three angels that visited Abraham at Sodom and Gomorrah. One of them was the LORD (God). How is it that Abraham was able to look upon the face of God? My understanding is that no one can look upon the glory of God.
The answer to your question can be found in Genesis 18:2 which says, “Abraham looked up and saw three men standing nearby.” Later we learn that it was the Lord and two angels, but it’s important to understand that all three were in human form. Since they appeared as humans, Abraham wasn’t seeing God and two angels in their glorified state, but rather three beings who looked like ordinary men. You might say they had disguised themselves in order to blend in with the local population since they were on their way to observe the behavior in Sodom and Gomorrah. The residents there were fooled by their disguises and treated the two angels disrespectfully. This confirmed reports the Lord had received about their sinfulness and sealed their fate.
