To be able to give thanks to God is to be able to have love of the world.

Thanking would lose meaning if we thanked for everything.
Thanking another person involves a value judgement: there must
be something worthy of thanks…. When the believer thanks
God for his creation, it seems to be a thanksgiving for his life as
a whole, for everything, including the good and evil within
his life, since despite such evil, thanking God is still said to be
possible. In devout religious believers, there seems to be no
questions of blaming God, but only of praising him….

To be able to give thanks to God is to be able to have love of the world.
(Concept of Prayer, P. 97)
