Is our love for GOD pure?

My love towards God is pure. I am really not after him for his promises, but I worship him for creating me. The very fact of own existence is the only reason for my love for God. How could I have existed if He hadn't caused me to exist. If I go on, there are many many countless things for which I am indebted to God in a number of ways. Everything is from him and is because of Him. I could not have existed if God hadn't decided it.
