Hebrews 11:1-3, 6, 33-40

Now faith is assurance of things hoped for, a conviction of things not seen. For therein the elders had witness borne to them. By faith we understand that the worlds have been framed by the word of God, so that what is seen hath not been made out of things which appear.

and without faith it is impossible to be well-pleasing unto him; for he that cometh to God must believe that he is, and that he is a rewarder of them that seek after him.

who through faith subdued kingdoms, wrought righteousness, obtained promises, stopped the mouths of lions, quenched the power of fire, escaped the edge of the sword, from weakness were made strong, waxed mighty in war, turned to flight armies of aliens. Women received their dead by a resurrection: and others were tortured, not accepting their deliverance; that they might obtain a better resurrection: and others had trial of mockings and scourgings, yea, moreover of bonds and imprisonment: they were stoned, they were sawn asunder, they were tempted, they were slain with the sword: they went about in sheepskins, in goatskins; being destitute, afflicted, ill-treated (of whom the world was not worthy), wandering in deserts and mountains and caves, and the holes of the earth. And these all, having had witness borne to them through their faith, received not the promise, God having provided some better thing concerning us, that apart from us they should not be made perfect.
