As in the time of the Egypt God's people were saved by putting, as a cross, the blood of a lamb on the doorposts.
How much more, shall we be saved at the end of all things being covered by the blood of the Messiah of Israel, Jesus.
Who was sacrificed for us, as of a lamb, without blemish and without spot.
And it will come, as in the time of Noah, but this time not of water but of fire.

1 Corinthians 5:7

For even Christ our passover lamb has been sacrificed for us:

Exodus 12:1-13

And the Lord spoke unto Moses and Aaron in the land of Egypt saying, This month shall be unto you the beginning of months: it shall be the first month of the year to you. Speak ye unto all the congregation of Israel, saying, In the tenth day of this month they shall take to them every man a lamb, according to the house of their fathers, a lamb for a house: And if the household be too little for the lamb, let him and his neighbour next unto his house take it according to the number of the souls; every man according to his eating shall make your count for the lamb. Your lamb shall be without blemish, a male of the first year: you shall take it out from the sheep, or from the goats: And you shall keep it up until the fourteenth day of the same month: and the whole assembly of the congregation of Israel shall kill it in the evening. And they shall take of the blood, and strike it on the two side posts and on the upper door post of the houses, wherein they shall eat it. And they shall eat the flesh in that night, roast with fire, and unleavened bread; and with bitter herbs they shall eat it. Eat not of it raw, nor sodden at all with water, but roast with fire; his head with his legs, and with the innards thereof. And ye shall let nothing of it remain until the morning; and that which remains of it until the morning you shall burn with fire. And thus shall you eat it; with your loins girded, your shoes on your feet, and your staff in your hand; and you shall eat it in haste: it is the Lord's passover. For I will pass through the land of Egypt this night, and will smite all the firstborn in the land of Egypt, both man and beast; and against all the gods of Egypt I will execute judgment: I am the Lord.
And the blood shall be to you for a token upon the houses where ye are: and when I see the blood, I will pass over you, and the plague shall not be upon you to destroy you, when I smite the land of Egypt.

Isaiah 11:10-11

And in that day there shall be a root of Jesse, which shall stand for an ensign of the people; to it shall the Gentiles seek: and his rest shall be glorious. It will also come about in that day that my Lord will again redeem - a second time with His hand - the remnant of His people who remain.

Isaiah 26:19-21

Thy dead men shall live, together with my dead body shall they arise. Awake and sing, ye that dwell in dust: for thy dew is as the dew of herbs, and the earth shall cast out the dead. Come, my people, enter thou into thy chambers, and shut thy doors about thee: hide thyself as it were for a little moment, until the indignation be overpast. For, behold, the Lord comes out of his place to punish the inhabitants of the earth for their iniquity: the earth also shall disclose her blood, and shall no more cover her slain.

Isaiah 13:9-11,13

Behold, the day of the Lord comes, cruel both with wrath and fierce anger, to lay the land desolate: and he shall destroy the sinners thereof out of it. For the stars of heaven and the constellations thereof shall not give their light: the sun shall be darkened in his going forth, and the moon shall not cause her light to shine. And I will punish the world for their evil, and the wicked for their iniquity; and I will cause the arrogancy of the proud to cease, and will lay low the haughtiness of the terrible.
Therefore I will shake the heavens, and the earth shall remove out of her place, in the wrath of the Lord of hosts, in the day of his fierce anger.

Isaiah 25:6-8

And in this mountain shall the Lord of hosts make unto all people a feast of fat things, a feast of wines on the lees, of fat things full of marrow, of wines on the lees well refined. And he will destroy in this mountain the face of the covering cast over all people, and the vail that is spread over all nations. He will swallow up death in victory; and the Lord God will wipe away tears from off all faces; and the rebuke of his people shall he take away from off all the earth: for the Lord hath spoken it.

1 Corinthians 15:1-4

Moreover, brethren, I declare unto you the gospel which I preached unto you, which also you have received, and wherein you stand;
By which also you are saved, if you keep in memory what I preached unto you, unless you have believed in vain. For I delivered unto you first of all that which I also received:
how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures:

"He that made the heavens and the earth: What is His name and what is the name of His Son - if you know?" Proverbs 30:4
Jesus is the Son of the Living God of Israel; "the Anointed One", Christ, Messiah, Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace. The Lamb of God.
In his death; his blood was poured out, as of a lamb without blemish nor spot, as a guilt offering for sin. In his burial; his innocent blood cried out with better words than those of Abel. He was raised from the dead the third day by the power of God: triumphing over evil once and for all time. And by his own blood he entered into the holy place in heaven. To present his blood on the mercy seat in front of his Father as a peace offering. And with the blood of sprinkling: God enjoins us to himself for all eternity. In the final day: The wrath of the Lord of hosts will passover those covered by his blood.

Revelation 1:5

And from Jesus Christ, who is the faithful witness, and the first begotten of the dead, and the prince of the kings of the earth. Unto him that loved us, and washed us from our sins in his own blood,

Romans 3:24-25,28;5:9;4:25

Being justified freely by his grace through the redemption that is in Christ Jesus: Whom God hath set forth to be a propitiation recieved through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; we conclude that a man is justified by faith without the deeds of the law. Much more then, being now justified by his blood, we shall be saved from the wrath of God through him. He was delivered for our iniquity & sin, and was raised again for our justification.

1 Peter 1:18-25

Forasmuch as you know that ye were not redeemed with corruptible things, such as silver and gold, nor from your vain conversation received by tradition from your fathers; But with the precious blood of Christ, as of a lamb without blemish and without spot: Who verily was foreordained before the foundation of the world, but was manifest in these last times for you, Who by him do believe in God, that raised him up from the dead, and gave him glory; that your faith and hope might be in God. Seeing you have purified your souls in obeying the truth through the Spirit unto unfeigned love of the brethren, see that you love one another with a pure heart enthusiastically: Being born again, not of corruptible seed, but of incorruptible, by the word of God, which lives and abideth for ever. For all flesh is as grass, and all the glory of man as the flower of grass. The grass withers, and the flower thereof falls away: But the word of the Lord endures for ever. And this is the word which by the gospel is preached unto you.

2 Peter 3:8-15

But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day. The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering toward us; not willing that any should perish, but that all should come to repentance. But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up. Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness, Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat? Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness. Wherefore, beloved, seeing that ye look for such things, be diligent that ye may be found of him in peace, without spot, and blameless. And account that the longsuffering of our Lord is salvation;

Hebrews 12:22-29

But you are come unto mount Sion, and unto the city of the living God, the heavenly Jerusalem, and to an innumerable company of angels, To the general assembly and church of the firstborn, which are written in heaven, and to God the Judge of all, and to the spirits of just men made perfect, And to Jesus the mediator of the new covenant, and to the blood of sprinkling, that speaks better things than that of Abel. See that you refuse not him that speaks. For if they who refused him that spake on earth did not escape: much more shall we not escape, if we turn away from him that speaks from heaven: Whose voice then shook the earth: but now he has promised, saying, Yet once more I shake not the earth only, but also heaven. And this word, Yet once more, signifies the removing of those things that are shaken, as of things that are made, that those things which cannot be shaken may remain. Wherefore we are receiving a kingdom which cannot be moved, let us have grace, whereby we may serve God acceptably with reverence and godly fear:
For our God is a consuming fire.
