'Seen' in the Bible

Now faith is the realization of what is hoped for, the proof of things not seen.

By faith we understand the worlds were created by the word of God, in order that what is seen did not come into existence from what is visible.

By faith Noah, having been warned about things not yet seen, out of reverence constructed an ark for the deliverance of his family, by which he pronounced sentence on the world and became an heir of the righteousness that comes by faith.
