Yes, it sure is uplifting! Gives you a nice overview of the situation. Unless you have a rigid belief system standing in the way you cannot avoid picking up the high vibrations emanating from these messages. If they were based on lies and non-integrity the vibrations would be low no matter how "happy and cheerful" the surface/language would be.
This is actually confirmable using the mystic/scientist
David Hawkins method and
scale:
Channeled messages with high integrity:
Sheldan Nidles weekly updates: calibrate on avarage above 500.
Mike Quinseys messages (3 times a week): calibrates on avarage above 500.
Matthews monthly messages: calibrates on avarage in the mid 400s.
(The reason "Matthews messages" calibrate a bit lower than the two other sources is perhaps that he touches upon "negative/dark" stuff in more detail than the two other sources).
