What we really believe is what our actions show that we believe.
When we realize that faith is not what we believe but what we do, then we have to take some account of our actions. Given what we profess, we may just have to change how we live, and that may mean that faith, in this sense of doing, is costly and risky.
If our faith demands high ideals, values, and beliefs that we respect and want for ourselves, then we will have to live into our beliefs, or live up to our faith.
Faith is thus neither an abstraction nor a consent to a formula of convictions. Faith is the expression of a vision that we then act out.
