Hebrews 12:18 For you have not come to what may be touched, a blazing fire and darkness and gloom and a tempest 19 and the sound of a trumpet and a voice whose words made the hearers beg that no further messages be spoken to them.

22 But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable angels in festal gathering, 23 and to the assembly of the firstborn who are enrolled in heaven, and to God, the judge of all, and to the spirits of the righteous made perfect, 24 and to Jesus, the mediator of a new covenant…

25 See that you do not refuse him who is speaking.

For if they did not escape when they refused him who warned them on earth, much less will we escape if we reject him who warns from heaven.

26 At that time his voice shook the earth, but now he has promised, “Yet once more I will shake not only the earth but also the heavens.”

… thus let us offer to God acceptable worship, with reverence and awe, 29 for our God is a consuming fire.

How much reverence and awe do you have for God Almighty?

Do you, dear believer, sometimes fail to remember in fear and trembling the Power of the risen Lord, Christ Jesus?

(It is no wonder that Jesus greeted fearful Apostles with the assurance: “Peace.”)

It is a fearful thing to fall into the hands of the living God. – Hebrews 10:21

The Disciples finally realized that Jesus had not established God’s Kingdom in Jerusalem at the time He entered its gates prior to His crucifixion; yet the Apostles knew that Jesus will return on the clouds as Judge of the Heavens and earth!

Prior to becoming Disciples of Jesus, some were disciples of John the Baptist who had preached:

Matthew 3:

10 Even now the axe is laid to the root of the trees. Every tree therefore that does not bear good fruit is cut down and thrown into the fire.

11 “I baptize you with water for repentance, but he who is coming after me is mightier than I, whose sandals I am not worthy to carry. He will baptize you with the Holy Spirit and fire.

12 His winnowing fork is in his hand, and he will clear his threshing floor and gather his wheat into the barn, but the chaff he will burn with unquenchable fire.”

If the burning fire of the conquering Christ was prepared by John; if the burning fire of the conquering Jesus was prepared by the Cross; if the Judgment and Kingdom were close at hand; then how much nearer now? You with ears to hear, hear.

Jesus’ Disciples wanted to know when, but the Lord would not reveal it.  Never-the-less as Jesus rose into the clouds promising His return, the Disciples were filled with awe and reverence for the risen Son of Man.

Well they knew all of what our Lord Jesus had warned and cautioned:

John 15:6 If anyone does not abide in me he is thrown away like a branch and withers; and the branches are gathered, thrown into the fire, and burned.

Luke 24:51 While he blessed them, he parted from them and was carried up into heaven. 52 And they worshiped him and returned to Jerusalem with great joy, 53 and were continually in the temple blessing God.
