1. Christ, who will appear a second time, apart from sin, for salvation to those who eagerly wait for Him (Heb 9:28)
    1 Cor 1:7, Phil 3:20, Titus 2:13, Mt 16:27, Mt 24:14, Jn 14:3, 1 Cor 15:23, 1 Thess 4:14-17, 2 Thess 1:7, Rev 3:11, Rev 19:11-16

We wait for Christ to work out our salvation. (Heb 9:28, 1 Cor 1:7, Phil 3:20, Titus 2:13, Mt 16:27)

Heb 9:28 So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation.

1 Cor 1:7 So that ye come behind in no gift; waiting for the coming of our Lord Jesus Christ:

Phil 3:20 For our conversation is in heaven; from whence also we look for the Saviour, the Lord Jesus Christ:

Titus 2:13 Looking for that blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ;

Mt 16:27 For the Son of man shall come in the glory of his Father with his angels; and then he shall reward every man according to his works.

When Jesus, the Christ, comes again, the living will receive Christ in the air, and the dead will be resurrected. (1 Cor 15:23, 1 Thess 4:14-17)

1 Cor 15:23 But every man in his own order: Christ the firstfruits; afterward they that are Christ’s at his coming.

1 Thess 4:14 For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him.
15 For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep.
16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:
17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.

Jesus, the Christ, is coming soon and must come to judge the world. (Rev 3:11, Rev 19:11-16)

Rev 3:11 Behold, I come quickly: hold that fast which thou hast, that no man take thy crown.

Rev 19:11 And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war.
12 His eyes were as a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself.
13 And he was clothed with a vesture dipped in blood: and his name is called The Word of God.
14 And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean.
15 And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God.
16 And he hath on his vesture and on his thigh a name written, King Of Kings, And Lord Of Lords.
