Theologians distinguish between God's decretive will and God's permissive will. The decretive will is God's decree that something come about, the permissive will is His allowing something to come about in the created order.

Thanking God doesn't indicate how something came about (decree or permission), only that God could have brought about something different and chose not to. Thus, any blessing, supernatural or natural, flows from the hand of God.
