This is a long way of saying that more than declarative faith is required of us.
Faith is the grace of God given to us. Works are our demonstration of love back to God. Works do not save, but faith alone, by the grace of God.
Declarative faith is the starting point. When you become a believer, then you are certainly told to live by certain principles, to do good works, to obey Him, to be righteous and holy. All that good stuff. But it begins with putting your faith and trust in Jesus as your saviour.
