B'resheet 8:20-21 Then Noach built an altar to the L-RD, and took of every clean animal and of every clean bird and offered burnt offerings on the altar. And the L-RD smelled the soothing aroma; and the L-RD said to Himself, "I will never again curse the ground on account of man, for the intent of man's heart is evil from his youth; and I will never again destroy every living thing, as I have done.
Here we see the L-rd mention original sin. Mankind cannot have spiritual peace with Adonai unless they have faith in G-d's Son whom He sent to spiritually save mankind from His wrath against our sin. Adonai had a problem. He loves us but hates sin. Because of His Holiness and that He is just, He has to punish our sin. We also cannot come near Him because of this sin. The good news is because Adonai sent His Son to die for us and take the punishment for our sin even to the point of death on the execution stake. Once we confess this with our mouths our relationship is restored with the Father and one day we will enter into the New Jerusalem and the city of the living G-d and nothing can keep us from entering and having fellowship with Him.
Rom 10:8-12 But what does it say? "The word is near you; it is in your mouth and in your heart," that is, the word of faith we are proclaiming: That if you confess with your mouth, "Jesus is Lord," and believe in your heart that G-d raised him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you confess and are saved. As the Scripture says, "Anyone who trusts in him will never be put to shame." NIV
There will be a new beginning and He will wipe away every tear from our eyes. Sin will be a thing of the past for us.
Rev 21:1-6 And I saw a new heaven and a new earth; for the first heaven and the first earth passed away, and there is no longer any sea. And I saw the holy city, new Jerusalem, coming down out of heaven from G-d, made ready as a bride adorned for her husband. And I heard a loud voice from the throne, saying, "Behold, the tabernacle of G-d is among men, and He shall dwell among them, and they shall be His people, and G-d Himself shall be among them, and He shall wipe away every tear from their eyes; and there shall no longer be any death; there shall no longer be any mourning, or crying, or pain; the first things have passed away. " And He who sits on the throne said, "Behold, I am making all things new." And He said, "Write, for these words are faithful and true." And He said to me, "It is done. I am the Alpha (Aleph) and the Omega (Tahv), the beginning and the end. I will give to the one who thirsts from the spring of the water of life without cost. "He who overcomes shall inherit these things, and I will be his G-d and he will be My son. NAS
Rev 7:15-17For this reason, they are before the throne of G-d; and they serve Him day and night in His temple; and He who sits on the throne shall spread His tabernacle over them. "They shall hunger no more, neither thirst anymore; neither shall the sun beat down on them, nor any heat; for the Lamb in the center of the throne shall be their shepherd, and shall guide them to springs of the water of life; and G-d shall wipe every tear from their eyes. " NAS
Jude 1:24-25 Now to Him who is able to keep you from stumbling, and to make you stand in the presence of His glory blameless with great joy, to the only G-d our Savior, through Yeshua HaMashiach (Jesus Christ) our L-rd, be glory, majesty, dominion and authority, before all time and now and forever. Amen. NAS
B'resheet 8:22 "While the earth remains, Seedtime and harvest, And cold and heat, And summer and winter, And day and night shall not cease." NAS
This is a promise of G-d. You don't have to worry that the sun won't come up tomorrow. When you are facing a long winter and don't think it will ever end, don't worry it will. We have G-d's promise.
