Here are some scriptures about the fact that the wicked will perish.
Ps 37:20 But the wicked shall perish, and the enemies of the LORD shall be as the fat of lambs: they shall consume; into smoke shall they consume away.
Ps 68:1 Let God arise, let his enemies be scattered: let them also that hate him flee before him. 2 As smoke is driven away, so drive them away: as wax melteth before the fire, so let the wicked perish at the presence of God. 3 But let the righteous be glad; let them rejoice before God: yea, let them exceedingly rejoice.
Ps 73:27 For, lo, they that are far from thee shall perish: thou hast destroyed all them that go a whoring from thee.
Ps 112:10 The wicked shall see it, and be grieved; he shall gnash with his teeth, and melt away: the desire of the wicked shall perish.
Isa 41:11 Behold, all they that were incensed against thee shall be ashamed and confounded: they shall be as nothing; and they that strive with thee shall perish. 12 Thou shalt seek them, and shalt not find them, even them that contended with thee: they that war against thee shall be as nothing, and as a thing of nought.
John 3:14 And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up:
15 That whosoever believeth in him should not perish, but have eternal life. 16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. 17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved. 18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
John 10:28 And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.
1 Cor 1:17 For Christ sent me not to baptize, but to preach the gospel: not with wisdom of words, lest the cross of Christ should be made of none effect. 18 For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God.
II Th 2:10 And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved. 11 And for this cause God shall send them strong delusion, that they should believe a lie: 12 That they all might be damned who believed not the truth, but had pleasure in unrighteousness.
2 Pet 2:12 But these, as natural brute beasts, made to be taken and destroyed, speak evil of the things that they understand not; and shall utterly perish in their own corruption;
2 Pet 3:9 The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance. 10 But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up. 11 Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness, 12 Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?
Jude 1:7 Even as Sodom and Gomorrha, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the vengeance of eternal fire.
Sodom and Gommorrha suffered the vengeance of eternal fire, they are no more, they perished. Who does not understand the concept of putting down an incurably sick animal? All who choose to reject life in Christ, have chosen to remain incurably diseased with sin which itself produces death, and is highly contagious. They will be put down, after receiving the just reward for their sins, which they chose over the forgiveness and life offered them through Christ. Justice ans mercy meet in Christ. God, through His Son Jesus Christ, has done everything He possibly could to save us, short of forcing it upon us. Those who refuse the their salvation purchased at such an infinite cost, the life of the Son of God, will receive judgment for their own sins and then be no more. this all by their own choice.
