When the people would not listen to God after they left Egypt God said it was not sacrifice or burnt offerings He wanted,but that they would obey His voice and it would go well with them!They however would not incline their ear unto His councel,therefore truth perished and they would not receive correction (Jeremiah 7:22-28). 22 For I spake not unto your fathers, nor commanded them in the day that I brought them out of the land of Egypt, concerning burnt offerings or sacrifices:23 But this thing commanded I them, saying, Obey my voice, and I will be your God, and ye shall be my people: and walk ye in all the ways that I have commanded you, that it may be well unto you.24 But they hearkened not, nor inclined their ear, but walked in the counsels and in the imagination of their evil heart, and went backward, and not forward.25 Since the day that your fathers came forth out of the land of Egypt unto this day I have even sent unto you all my servants the prophets, daily rising up early and sending them:26 Yet they hearkened not unto me, nor inclined their ear, but hardened their neck: they did worse than their fathers.27 Therefore thou shalt speak all these words unto them; but they will not hearken to thee: thou shalt also call unto them; but they will not answer thee.28 But thou shalt say unto them, This is a nation that obeyeth not the voice of the Lord their God, nor receiveth correction: truth is perished, and is cut off from their mouth.
Since the Israelites left Egypt God has given man divine intervention through His holy spirit by the faith we hold in the Lord Jesus Christ!(John 16:7-15). 7 Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you.8 And when he is come, he will reprove the world of sin, and of righteousness, and of judgment:9 Of sin, because they believe not on me;10 Of righteousness, because I go to my Father, and ye see me no more;11 Of judgment, because the prince of this world is judged.12 I have yet many things to say unto you, but ye cannot bear them now.13 Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come.14 He shall glorify me: for he shall receive of mine, and shall shew it unto you.15 All things that the Father hath are mine: therefore said I, that he shall take of mine, and shall shew it unto you.
2 Timothy 3:14-17 14 But continue thou in the things which thou hast learned and hast been assured of, knowing of whom thou hast learned them;15 And that from a child thou hast known the holy scriptures, which are able to make thee wise unto salvation through faith which is in Christ Jesus.16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:17 That the man of God may be perfect, thoroughly furnished unto all good works. (2 Peter 1:19-21)
