The Baal Shem Tov teaches that everything which a person sees or hears serves as a lesson for him in his relationship with GD. Since everything that happens in this world is controlled by Divine providence, and man was “created solely to serve his Creator,” it follows that any and every event or entity that a person encounters is intended to help him advance his relationship with GD.

Gol al Hashem darkecha - Commit your way to Hashem (Tehillim 37:5)
The word "gol" has the same root as the word "hitgalut" (revelation), indicating that you should reveal your ways and character, examine them, and see that they are utilized for serving H'shem.
U'vetach alav - And trust in Him, the exaltedness and greatness of GD that you are looking to see in the world. That is what is called "trust". You will see H'shem's hand in the world, and thus trust in Him that everything happens for the best.
V'hu ya'aseh - And He shall do for you. Then He will do for you and create for you experiences that you have never previously encountered, * And "He will bring forth your righteousness like a light".
