James 2:17 says: So also faith, if it has no works, is dead in itself.
Faith is a certainty of what is expected, accumulated strength, moral conviction and security in what we believe. As children of God we must live by faith and make it evident in actions. We are saved by faith and without it we can not please the Lord, but it is only complete if we show it with works. In the church we have many leaders but those who activate their faith and intercede for others are also needed to witness to the power of the Lord. We need works because on earth there is much to be done, in heaven everything is done.
