2Cor.4.18  because we look not to the things that are seen but to the things that are unseen; for the things that are seen are transient, but the things that are unseen are eternal.
Heb.11.7  By faith Noah, being warned by God concerning events as yet unseen, took heed and constructed an ark for the saving of his household; by this he condemned the world and became an heir of the righteousness which comes by faith.
