She's not dead / She is sleeping

The "She's not dead / She is sleeping" is a story item that was added in update v0.51 of The Forest.

Gameplay
"She's not dead / She is sleeping" note is written on a Bible page. It can be found deep within Cave 7, next to a shrine dedicated to the Red Man. Upon encounter, the player will examine the item before adding it to the notes section of the survival guide.

It is very similar to the "Don't be afraid / Just believe" note, which was also probably written by Dr. Cross.

Theory
It is assumed that the note was authored by Dr. Cross, as it appears to reference his daughter, Megan. Megan is, in fact, dead, and not just sleeping, prior to the events of the story. However, as Dr. Cross knows of the existence of the resurrection obelisk, he most likely sees her death as a very temporary thing, hence him referring to her interim status as "sleeping". Regardless, this note implies that he is not completely mentally stable following her death.

Translation of Bible page
...themselves unto the righteousness of God. For Christ is the end of the law for righteousness to every one that believeth. For Moses describeth the righteousness which is of the law, That the man which doeth those things shall live by them. But the righteousness which is of faith speaketh on this wise, Say not in thine heart, Who shall ascend into heaven that is, to bring Christ down from above or, Who shall descend into the deep that is, to bring up Christ again from the dead. But what saith it The word is nigh thee, even in thy mouth, and in thy heart that is, the word of faith, which we preach that if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. For with the heart man believeth unto righteousness and with the mouth confession is made unto salvation. For the Scripture saith, Whosoever believeth on him shall not be ashamed. For there is no difference between the Jew and the Greek for the same Lord over all is rich unto all that call upon him. For whosoever shall call upon the name of the Lord shall be saved. How then shall they call on him in whom they have not believed and how shall they believe in him of whom they have not Heard and how shall they hear without a preacher and how shall they preach, except they be sent as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things But they have not all obeyed the gospel. For Isaiah saith, Lord, who hath believed our report. Romans 11 So then faith cometh by hearing, and hearing by the word of God. But I say, Have they not heard Yes verily, Their sound went into all the earth, and their words unto the ends of the world. But I say, Did not Israel know First Moses saith, I will provoke you to jealousy by them that are no people, and by a foolish nation I will anger you. But Isaiah is very bold, and saith, I was found of them that sought me not I was made manifest unto them that asked not after me. But to Israel he saith, All day long I have stretched forth my hands unto a disobedient and gainsaying people. The Remnant of Israel I say then, Hath God cast away his people God forbid. For I also am an Israelite, of the seed of Abraham, of the tribe of Benjamin. God hath not cast away his people which he foreknew. Wot ye not what the Scripture saith of Elijah how he maketh intercession to God against Israel, saying, Lord, they have killed thy prophets and digged down thine altars and I am left alone, and they seek my life. But what saith the answer of God unto him I have reserved to myself seven thousand men, who have not bowed the knee to the image of Baal. Even so then at this present time also there is a remnant according to the election of grace. And if by grace, then is it no more of works otherwise grace is no more grace. But if it be of works, then is it no more grace otherwise work is no more work. What then Israel hath not obtained that which he seeketh for but the election hath obtained it, and the rest were blinded according as it is written, God hath given them the spirit of slumber, eyes that they should not see, and ears that they should not hear unto this day. And David saith, Let their table be made a snare, and a trap, and a stumblingblock, and a recompense unto them let their eyes be darkened, that they may not see, and bow down their back alway. The Salvation of the Gentiles I say then, Have they stumbled that they should fall God forbid but rather through their fall salvation is come unto the Gentiles, for to provoke them to jealousy. Now if the fall of them be the riches of the world, and the diminishing of them the riches of the Gentiles how much more their fulness For I speak to you Gentiles,…
