Vanderhoven,
I can't give you such scriptures because, there are no such scriptures.
What I can tell is that everyone is saved and justified in in the same way trough Jesus's blood and He is the mediator for all who believe. However, salvation comes in stages and there is a ruling class that will be in heaven with Jesus which is being saved first.
"Do not be afraid, little flock, because your Father has chosen to give you the kingdom." Luke 12:32
"just as the Father knows Me and I know the Father; and I lay down My life for the sheep. And I have other sheep that are not of this fold; I must bring them also, and they will listen to My voice; and they will become one flock, with one shepherd."John 10:15-16
"The statement is trustworthy: For if we died with Him, we will also live with Him; If we endure, we will also reign with Him; If we deny Him, He will also deny us;"
2 Timothy 2:11-12
"And if I go and prepare a place for you, I am coming again and will take you to Myself, so that where I am, there you also will be."John 14:3
"Then I looked, and behold, the Lamb was standing on Mount Zion, and with Him 144,000 who had His name and the name of His Father written on their foreheads. And they *sang a new song before the throne and before the four living creatures and the elders; and no one was able to learn the song except the 144,000 who had been purchased from the earth. These are the ones who have not defiled themselves with women, for they are celibate. These are the ones who follow the Lamb wherever He goes. These have been purchased from mankind as first fruits to God and to the Lamb.Revelation 14:1, 3-4
"But you are a chosen people, a royal priesthood, a holy nation, a people for God’s own possession, so that you may proclaim the excellencies of Him who has called you out of darkness into His marvelous light; for you once were not a people, but now you are the people of God; you had not received mercy, but now you have received mercy."
1 Peter 2:9-10
Not everyone will go to heaven to rule with Jesus but the exact number of 144000 who are the bride of Christ.
Salvation comes in stages.
First those that belongs to the heavenly Jerusalem will be sealed. One can say they are all from the house of Israel.
"For he is not a Jew who is one outwardly, nor is circumcision that which is outward in the flesh. But he is a Jew who is one inwardly; and circumcision is of the heart, by the Spirit, not by the letter; and his praise is not from people, but from God." Romans 2:28-29
After the 144 000 are sealed the great tribulation will come and everyone of the great crowd that will be found faithful will be saved as well by Jesus.
"After these things I looked, and behold, a great multitude which no one could count, from every nation and all the tribes, peoples, and languages, standing before the throne and before the Lamb, clothed in white robes, and palm branches were in their hands; and they *cried out with a loud voice, saying, “Salvation belongs to our God who sits on the throne, and to the Lamb.”
Revelation 7:9-10
After the first vision of the sealing of the 144000 John has another vision following the first one where he sees the great crowd crying for salvation. (I like a lot this part of the vision). This group comes later in the vision and they are not numbered, neither in line to rule with Jesus ,whereas the 144000 they are purchased from earth and they are the first fruits to God and the Lamb.
"Blessed and holy is the one who has a part in the first resurrection; over these the second death has no power, but they will be priests of God and of Christ, and will reign with Him for a thousand years."
Revelation 20:6
There is also an royal wedding mentioned in the bible in several places.
"You have loved righteousness and hated wickedness; Therefore God, Your God, has anointed You With the oil of joy above Your companions. All Your garments are fragrant with myrrh, aloes, and cassia; From ivory palaces stringed instruments have made You joyful. Kings’ daughters are among Your noble women; At Your right hand stands the queen in gold from Ophir. Listen, daughter, look and incline your ear: Forget your people and your father’s house; Then the King will crave your beauty. Because He is your Lord, bow down to Him. The King’s daughter is all glorious within; Her clothing is interwoven with gold. She will be brought to the King in colorful garments; The virgins, her companions who follow her, Will be brought to You.
Psalms 45:7-11, 13-14
"For I am jealous for you with a godly jealousy; for I betrothed you to one husband, to present you as a pure virgin to Christ." 2 Corinthians 11:2
"Then I heard something like the voice of a great multitude and like the sound of many waters, and like the sound of mighty peals of thunder, saying, “Hallelujah! For the Lord our God, the Almighty, reigns. Let’s rejoice and be glad and give the glory to Him, because the marriage of the Lamb has come, and His bride has prepared herself.” It was given to her to clothe herself in fine linen, bright and clean; for the fine linen is the righteous acts of the saints. Then he *said to me, “Write: ‘Blessed are those who are invited to the wedding feast of the Lamb.’ ” And he *said to me, “These are the true words of God.”
Revelation 19:6-9
At this marriage between the Lamb and the Church are invited many others which are not of the bride class but are companions to the queen.
