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

Now faith is the substance of things hoped for, the evidence of things not seen. For by it the elders obtained a good testimony. By faith we understand that the worlds were framed by the word of God, so that the things which are seen were not made of things which are visible.

But without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him.

who through faith subdued kingdoms, worked righteousness, obtained promises, stopped the mouths of lions, quenched the violence of fire, escaped the edge of the sword, out of weakness were made strong, became valiant in battle, turned to flight the armies of the aliens. Women received their dead raised to life again. Others were tortured, not accepting deliverance, that they might obtain a better resurrection. Still others had trial of mockings and scourgings, yes, and of chains and imprisonment. They were stoned, they were sawn in two, were tempted, were slain with the sword. They wandered about in sheepskins and goatskins, being destitute, afflicted, tormented— of whom the world was not worthy. They wandered in deserts and mountains, in dens and caves of the earth. And all these, having obtained a good testimony through faith, did not receive the promise, God having provided something better for us, that they should not be made perfect apart from us.
