Faith is the substance of things hoped for......
the evidance of things not seen. Heb 11:1

Without hope (hopelessness) faith can not work.
Our hope to be healed, delivered, prosperous will
cause our faith to bring substance to it.

Our faith gives substance to and brings the
manifestations of the things we hope for that is
ours through the covenant.

So by speaking God's word continuously it causes
our faith to bring the things we hope for.
