Faith is the seed, faith gives us hope in this dark world. 'Faith is the substance of things hoped for'. In other words we can have faith in many things, some people can have faith in things that are completely false but only when we have faith in what is true is there any substance behind it. If we have faith in Christ, which starts as hope that all that he taught is true, then he will guide us to him, and then your faith has transformed into knowledge. Pure faith in Christ becomes the experience of Christ, then you know Christ.
