What faith is.
Hebrews 11:1 Now faith is the substance of things hoped for, the evidence of things not seen. Hebrews 11:2 For by it the elders obtained a good report. Hebrews 11:3 Through faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which appeared. Hebrews 11:4 By faith Abel offered to God a more excellent sacrifice than Cain, by which he obtained testimony that he was righteous, God testifying of his gifts: and by it he being dead yet speaketh. Hebrews 11:5 By faith Enoch was translated, that he should not see death; and was not found, because God had translated him: for before his translation he had this testimony, that he pleased God.
Without faith we cannot please God.
Hebrews 11:6 But without faith [it is] impossible to please [him]: for he that cometh to God must believe that he is, and [that] he is a rewarder of them that diligently seek him.
The worthy fruits thereof in the fathers of old time.
Hebrews 11:7 By faith Noah, being warned by God of things not seen as yet, moved with fear, prepared an ark to the saving of his house; by which he condemned the world, and became heir of the righteousness which is by faith. Hebrews 11:8 By faith Abraham, when he was called to remove into a place which he should afterwards receive for an inheritance, obeyed; and he went out not knowing whither he was going. Hebrews 11:9 By faith he sojourned in the land of promise, as [in] a foreign country, dwelling in tabernacles with Isaac and Jacob, the heirs with him of the same promise: Hebrews 11:10 For he looked for a city which hath foundations, whose builder and maker [is] God. Hebrews 11:11 Through faith also Sarah herself received strength to conceive seed, and was delivered of a child when she was past age, because she judged him faithful who had promised. Hebrews 11:12 Therefore there sprang even from one, and him as good as dead, [so many] as the stars of the sky in multitude, and as the sand which is by the sea-shore innumerable. Hebrews 11:13 These all died in faith, not having received the promises, but having seen them afar off, and were persuaded of [them], and embraced [them], and confessed that they were strangers and pilgrims on the earth. Hebrews 11:14 For they that say such things declare plainly that they seek a country. Hebrews 11:15 And truly, if they had been mindful of that [country] from whence they came, they might have had opportunity to return. Hebrews 11:16 But now they desire a better [country], that is, a heavenly: wherefore God is not ashamed to be called their God; for he hath prepared for them a city. Hebrews 11:17 By faith Abraham, when he was tried, offered up Isaac: and he that had received the promises offered up his only-begotten [son], Hebrews 11:18 Of whom it was said, That in Isaac shall thy seed be called: Hebrews 11:19 Accounting that God [was] able to raise [him] even from the dead; from whence also he received him in a figure. Hebrews 11:20 By faith Isaac blessed Jacob and Esau concerning things to come. Hebrews 11:21 By faith Jacob, when he was dying, blessed both the sons of Joseph; and worshiped, [leaning] upon the top of his staff. Hebrews 11:22 By faith Joseph, when he died, made mention of the departing of the children of Israel; and gave commandment concerning his bones. Hebrews 11:23 By faith Moses when he was born, was hid three months by his parents, because they saw [he was] a proper child; and they were not afraid of the king's commandment. Hebrews 11:24 By faith Moses, when he had come to years, refused to be called the son of Pharaoh's daughter; Hebrews 11:25 Choosing rather to suffer affliction with the people of God, than to enjoy the pleasures of sin for a season; Hebrews 11:26 Esteeming the reproach of Christ greater riches than the treasures of Egypt: for he had respect to the recompense of the reward. Hebrews 11:27 By faith he forsook Egypt, not fearing the wrath of the king: for he endured, as seeing him who is invisible. Hebrews 11:28 Through faith he kept the passover, and the sprinkling of blood, lest he that destroyed the first-born should touch them. Hebrews 11:29 By faith they passed through the Red sea as by dry [land]: which the Egyptians essaying to do were drowned. Hebrews 11:30 By faith the walls of Jericho fell down after they had been encompassed seven days. Hebrews 11:31 By faith the harlot Rahab perished not with them that believed not, as she had received the spies with peace. Hebrews 11:32 And what shall I say more? for the time would fail me to tell of Gideon, and [of] Barak, and [of] Samson, and [of] Jephthah, [of] David also, and Samuel, and [of] the prophets: Hebrews 11:33 Who through faith subdued kingdoms, wrought righteousness, obtained promises, stopped the mouths of lions, Hebrews 11:34 Quenched the violence of fire, escaped the edge of the sword, out of weakness were made strong, became valiant in fight, turned to flight the armies of the aliens. Hebrews 11:35 Women received their dead raised to life again: and others were tortured, not accepting deliverance; that they might obtain a better resurrection: Hebrews 11:36 And others had trial of [cruel] mockings and scourgings, and, moreover of bonds and imprisonment: Hebrews 11:37 They were stoned, they were sawn asunder, were tempted, were slain with the sword: they wandered about in sheep-skins, and goat-skins; being destitute, afflicted, tormented; Hebrews 11:38 (Of whom the world was not worthy:) they wandered in deserts, and [in] mountains, and [in] dens and caves of the earth. Hebrews 11:39 And these all, having obtained a good report through faith, received not the promise: Hebrews 11:40 God having provided some better [thing] for us, that they without us should not be made perfect.
