Belief is the system that forms what we know with total and absolute certainty.
The belief feeds our THOUGHT process with all the useful/certain information it stands for.
The THOUGHT influences how we feel per time. Whatever you feel is as a result of your THOUGHT.
The FEELING now goes on to influence the way we react/act (BEHAVIOR) to various situations.
Finally, the BEHAVIOR drives action/reaction & activates the result of that action.
