James 2:14-17, James 2:26 (NIV)
14What good is it, my brothers, if a man claims to have faith but has no deeds? Can such faith save him?
15Suppose a brother or sister is without clothes and daily food.
16If one of you says to him, “Go, I wish you well; keep warm and well fed,” but does nothing about his physical needs, what good is it?
17In the same way, faith by itself, if it is not accompanied by action, is dead.
26As the body without the spirit is dead, so faith without deeds is dead.
Revelation 3:1-6 (NIV)
1“To the angel of the church in Sardis write: These are the words of him who holds the seven spirits of God and the seven stars. I know your deeds; you have a reputation of being alive, but you are dead.
2Wake up! Strengthen what remains and is about to die, for I have not found your deeds complete in the sight of my God.
3Remember, therefore, what you have received and heard; obey it, and repent. But if you do not wake up, I will come like a thief, and you will not know at what time I will come to you.
4Yet you have a few people in Sardis who have not soiled their clothes. They will walk with me, dressed in white, for they are worthy.
5He who overcomes will, like them, be dressed in white. I will never blot out his name from the book of life, but will acknowledge his name before my Father and his angels.
6He who has an ear, let him hear what the Spirit says to the churches.
