“After this I saw four angels standing at the four corners of the earth, holding back the four winds of the earth to prevent any wind from blowing on the land or on the sea or on any tree.  Then I saw another angel coming up from the east, having the seal of the living God. He called out in a loud voice to the four angels who had been given power to harm the land and the sea: “Do not harm the land or the sea or the trees until we put a seal on the foreheads of the servants of our God.” ⁴Then I heard the number of those who were sealed: 144,000 from all the tribes of Israel.” Revelation 7:1-4

“Then I looked, and there before me was the Lamb, standing on Mount Zion, and with him 144,000 who had his name and his Father’s name written on their foreheads.  And I heard a sound from heaven like the roar of rushing waters and like a loud peal of thunder. The sound I heard was like that of harpists playing their harps.  And they sang a new song before the throne and before the four living creatures and the elders. No one could learn the song except the 144,000 who had been redeemed from the earth. These are those who did not defile themselves with women, for they remained virgins. They follow the Lamb wherever he goes. They were purchased from among mankind and offered as first fruits to God and the Lamb.  No lie was found in their mouths; they are blameless.” Revelation 14:1-5

“And you also were included in Christ when you heard the message of truth, the gospel of your salvation. When you believed, you were marked in him with a seal, the promised Holy Spirit, who is a deposit guaranteeing our inheritance until the redemption of those who are God’s possession—to the praise of his glory.” Ephesians 1:13-14

“Place me like a seal over your heart,
like a seal on your arm;
for love is as strong as death,
its jealousy unyielding as the grave.
It burns like blazing fire,
like a mighty flame.

 Many waters cannot quench love;
rivers cannot sweep it away.
If one were to give
all the wealth of one’s house for love,
it would be utterly scorned.  Song of Solomon 8: 6-7

“In order to endure the trial before them, all must understand the will of God as revealed in His word; all can honor Him only as they have a right conception of His character, government, and purposes, and act in accordance with them. None but those who have fortified the mind with the truths of the Bible will stand through the last great conflict… The decisive hour is even now at hand. Are our feet planted on the rock of God’s immutable word? Are we prepared to stand firm in defense of the commandments of God and the faith of Jesus?” GC 593
