Trust in Hashem is like an insurance policy.  A person can have a policy granting coverage for $1000, $10,000 or $100,000, depending on how much a person is willing to pay.  The larger the policy, the more the person is covered.  Similarly, the insurance we receive from Hashem depends upon the amount of trust we place in Him.  The pasuk in Yirmiyahu states:

ברוך הגבר אשר יבטח בה’ והיה ה’ מבטחו – “Fortunate is the man who trusts in Hashem, and Hashem will be his guarantor.”  This means that Hashem will be a person’s guarantor because he places his trust in Him.

Thus one who places abundant trust in Hashem is fortunate, because he receives the ultimate “coverage.” ~ based on the Baal Shem Tov zt”l
