Most assuredly. That is, if you are talking about the ability of man, on his own, deciding to follow Jesus. The Bible is full of scripture that says that man cannot come to God on his own volition. It is God who calls, it is God who predestines, it is God who saves.
However, what you have written so far is quite similar to what I just read in a book titled "Spiritual Combat Revisited." To quote, "The [Catholic] Church understands this [James 1: 17] to mean that left to ourselves, we cannot please God and inherit eternal life." Also, "There is a tendency we all have to claim our good actions as our own and the bad things we do as not pertaining to ourselves in the same way. The truth is the reverse: The good things we do are the result of God's grace and mercy, and the evil things we do are the sign of what we really are."
