James 2:24 and 26

You see that a man (believer) is justified by works and not by faith alone (that is, by acts of obedience, a born-again believer reveals his faith). (26) For just as the (human) body without the spirit is dead, so faith without works (of obedience) is also dead.

We are to be active believers of Jesus. An active believer studies the word, absorbs the information in the heart, and believes that what the word says is true and attainable through faith. If we are not doing and obeying the word, we will not see results from the word.
