What is faith?
1. Faith is something completely different from “works” (v.3-8)
2. Faith does not depend on any religious ceremony (v.9-12)
3. Faith is not related to the law (v.13-17)
4. Faith often rests in a promise that flies in the face of what is natural and normal (v.18-22)

“And therein lies the secret of faith: faith is always strong or weak depending on how we perceive the object of our faith. Is the God to whom we look weak in our eyes? Then we will have weak faith. Is our God strong in our eyes? Then our faith will grow strong accordingly. There was nothing in Abraham that gave him strong faith, but there was everything in God that gave him strong faith.”
