Hebrews 11:1-4

Now faith is the assurance (title deed, confirmation) of things hoped for (divinely guaranteed), and the evidence of things not seen [the conviction of their reality—faith comprehends as fact what cannot be experienced by the physical senses]. For by this [kind of] faith the men of old gained [divine] approval. By faith [that is, with an inherent trust and enduring confidence in the power, wisdom and goodness of God] we understand that the worlds (universe, ages) were framed and created [formed, put in order, and equipped for their intended purpose] by the word of God, so that what is seen was not made out of things which are visible. By faith Abel offered to God a more acceptable sacrifice than Cain, through which it was testified of him that he was righteous (upright, in right standing with God), and God testified by accepting his gifts. And though he died, yet through [this act of] faith he still speaks. [Gen 4:3-10]
