Psalm 91

I think psalm 91 is very confusing to many Christians. Because Satan quotes verses 11 and 12 applying to Christ we might be tempted to consider this psalm wholly Messianic. But I'm not sure we want to trust the liar's interpretation. I think the psalm applies to any and all who submit themselves to the command of Jesus. What Jesus makes clear in the satanic encounter is that God does not limit his protection to the physical realm. Satan also ignored verse 13 where the believer will have victory over the serpent. A not so veiled reference to that lying accuser.
