Trust

The whole phenomenon of trust and hope is a very illogical one.  Nothing exemplifies this more than the following verse from Hebrews (10:23):

Let us keep firm in the hope we profess, because the one who made the promise is faithful. 

We persevere in hope not because we trust in our capabilities or strength but because we trust God to be faithful - even if we are not! 

Contrast this with one Anthony DeMello's quotes:

A bird sitting on a tree is never afraid of the branch breaking, because her trust is not on the branch but on it's wings. 

Perhaps the only difference here is that trust is not in a material object but a living person.  Only that logic makes sense - some sense.  But still this aspect of trust can never be fully explained away.  Nonetheless we trust.  We hope!
