Faith is not something you do to make God respond. Studying the Bible, confessing the Word, acting on the Word are all involved in the faith process, but it's not faith. One of the reasons why people aren't receiviing more from the Lord is they think "faith" is God responding to something that they do. Faith is simply a positive response to what God has already provided by his grace.
According to the Word, God has already blessed us with every spiritual blessing in heavenly places (Ephesians 1:2). We now have to simply respond by acting like it's true because it is true in the eyes of God.
