Debating Jesus' Intentions

The story of Jesus' debate with Satan would have been better had it not ended with angels coming to minister.  It seems to diminish the value of the forty days of the desert and makes it rather more shallow than it should be.  The debate with Satan has a similar cast, but it is overshadowed by the angelic intrusion.  It would be hard for anyone, even Satan, to have taken seriously a discussion with such a blatant ending.  He would have had to assume he was there for show rather than for any serious, or even less so Satanic, purpose.
