The following scriptures are very scary and sobering. What should our response (as born again believers in Christ) be?

Revelation 21:8

But as for the cowardly, the faithless, the detestable, as for murderers, the sexually immoral, sorcerers, idolaters, and all liars, their portion will be in the lake that burns with fire and sulfur, which is the second death.

Galatians 5:19-21

19 Now the doings (practices) of the flesh are clear (obvious): they are immorality, impurity, indecency,

20 Idolatry, sorcery, enmity, strife, jealousy, anger (ill temper), selfishness, divisions (dissensions), party spirit (factions, sects with peculiar opinions, heresies),

21 Envy, drunkenness, carousing, and the like. I warn you beforehand, just as I did previously, that those who do such things shall not inherit the kingdom of God.

Galatians 5:3-6

3 But immorality (sexual vice) and all impurity [[b]of lustful, rich, wasteful living] or greediness must not even be named among you, as is fitting and proper among saints (God’s consecrated people).

4 Let there be no filthiness (obscenity, indecency) nor foolish and sinful (silly and corrupt) talk, nor coarse jesting, which are not fitting or becoming; but instead voice your thankfulness [to God].

5 For be sure of this: that no person practicing sexual vice or impurity in thought or in life, or one who is covetous [who has lustful desire for the property of others and is greedy for gain]—for he [in effect] is an idolater—has any inheritance in the kingdom of Christ and of God.

6 Let no one delude and deceive you with empty excuses and groundless arguments [for these sins], for through these things the wrath of God comes upon the sons of rebellion and disobedience.
