I will walk by Faith
Amen, faith saved them and they had to do something in order to remain saved, unlike Christians who just want faith and no works to keep that faith going. James 2: 14] What doth it profit, my brethren, though a man say he hath faith, and have not works? can faith save him?  If a brother or sister be naked, and destitute of daily food,  And one of you say unto them, Depart in peace, be ye warmed and filled; notwithstanding ye give them not those things which are needful to the body; what doth it profit?  Even so faith, if it hath not works, is dead, being alone.  Yea, a man may say, Thou hast faith, and I have works: shew me thy faith without thy works, and I will shew thee my faith by my works.  Thou believest that there is one God; thou doest well: the devils also believe, and tremble.  But wilt thou know, O vain man, that faith without works is dead?  Was not Abraham our father justified by works, when he had offered Isaac his son upon the altar?  Seest thou how faith wrought with his works, and by works was faith made perfect?  And the scripture was fulfilled which saith, Abraham believed God, and it was imputed unto him for righteousness: and he was called the Friend of God.  Ye see then how that by works a man is justified, and not by faith only.  Likewise also was not Rahab the harlot justified by works, when she had received the messengers, and had sent them out another way?  For as the body without the spirit is dead, so faith without works is dead also.
Jesus the Son of God healed people according their faith. Matthew 9: 27] And when Jesus departed thence, two blind men followed him, crying, and saying, Thou Son of David, have mercy on us.  And when he was come into the house, the blind men came to him: and Jesus saith unto them, Believe ye that I am able to do this? They said unto him, Yea, Lord.  Then touched he their eyes, saying, According to your faith be it unto you.  And their eyes were opened; and Jesus straitly charged them, saying, See that no man know it. Luke 7: 47] Wherefore I say unto thee, Her sins, which are many, are forgiven; for she loved much: but to whom little is forgiven, the same loveth little.  And he said unto her, Thy sins are forgiven.  And they that sat at meat with him began to say within themselves, Who is this that forgiveth sins also?  And he said to the woman, Thy faith hath saved thee; go in peace.
Nice Philosophy and vain deceit by pocketbook preachers and not bible. Faith is something we can not see but hoped for. A $100.00 bill is not faith that is sight. Faith is when you put the Gospel of Christ words to work and it works for you right on time. Something or issue afar that we can not see, and we get a response right on time. Romans 10:  So then faith cometh by hearing, and hearing by the word of God. 2nd Cor 5:  (For we walk by faith, not by sight:) Romans 1: 16] For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek.  For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith. Hebrews 11:  Now faith is the substance of things hoped for, the evidence of things not seen.  For by it the elders obtained a good report.  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 do appear.  By faith Abel offered unto God a more excellent sacrifice than Cain, by which he obtained witness that he was righteous, God testifying of his gifts: and by it he being dead yet speaketh.  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.  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.
