The word "faith" appears only twice in the Old Testament (King James Version), but Jesus talks about it 29 times in the gospels. Faith and works have to go hand-in-hand. We must acknowledge the Lord God, divine and omnipotent (faith), and we must go and live a life in which we "love our neighbor as ourselves," (works), following the path He laid out for us. If we do that, He will gradually remove the love of evil from us and replace it with a love of doing what's good. When the Lord speaks of "faith" in the Bible, then, he's talking about the first of these two steps. Like the people of Jesus's day, we need to acknowledge –- to have faith -- that the Lord is God Himself, divine and omnipotent. That is the beginning point of a truly spiritual life, but we can't stop there. Time and again, Jesus says things like "Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven" (Matthew 7:21), "if thou wilt enter into life, keep the commandments" (Matthew 19:17) and "whosoever shall do the will of God, the same is my brother, and my sister, and mother" (Mark 3:35).
