First let's look at what faith is not: Faith is not an emotion. For example, if you're a Christian then you have faith in Jesus as your Savior, but you're not constantly full of emotion and shouting and jumping and so on. Faith can sometimes bring out emotion in us, but faith itself is not an emotion. Faith is not knowledge. For example, when Hurricane Ike was heading towards Houston in September, 2008, Someone asked the Lord if he should evacuate from Houston or do something to protect his house. He believed that He told him not to do either of those things, so he had faith that his house would be unharmed. After the hurricane passed across Houston without damaging his house, at that point he had knowledge that his house was unharmed. He no longer needed to have faith that his house would be unharmed. This demonstrates that faith is different from knowledge. Faith is not hope: 1 Corinthians 13:13: "And now these three remain: faith, hope and love. But the greatest of these is love." As the above verse shows, faith is different from hope.
