And Jesus said to him, “‘If you can’! All things are possible for one who believes.” Immediately the father of the child cried out and said, “I believe; help my unbelief!” And when Jesus saw that a crowd came running together, he rebuked the unclean spirit, saying to it, “You mute and deaf spirit, I command you, come out of him and never enter him again.”
Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God. And this is the judgment: the light has come into the world, and people loved the darkness rather than the light because their works were evil.
2 Thessalonians 2:11-12
Therefore God sends them a strong delusion, so that they may believe what is false, in order that all may be condemned who did not believe the truth but had pleasure in unrighteousness.
The one who rejects me and does not receive my words has a judge; the word that I have spoken will judge him on the last day.
Whoever believes and is baptized will be saved, but whoever does not believe will be condemned.
And have mercy on those who doubt;
Then he said to Thomas, “Put your finger here, and see my hands; and put out your hand, and place it in my side. Do not disbelieve, but believe.” Thomas answered him, “My Lord and my God!” Jesus said to him, “Have you believed because you have seen me? Blessed are those who have not seen and yet have believed.”
2 Timothy 3:5
Having the appearance of godliness, but denying its power. Avoid such people.
1 John 2:15-17
Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him. For all that is in the world—the desires of the flesh and the desires of the eyes and pride in possessions—is not from the Father but is from the world. And the world is passing away along with its desires, but whoever does the will of God abides forever.
For by grace you have been saved through faith. And this is not your own doing; it is the gift of God,
“Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but the one who does the will of my Father who is in heaven."
But let him ask in faith, with no doubting, for the one who doubts is like a wave of the sea that is driven and tossed by the wind.
He said to them, “Because of your little faith. For truly, I say to you, if you have faith like a grain of mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move, and nothing will be impossible for you.”
For many are called, but few are chosen.
All these things my hand has made, and so all these things came to be, declares the Lord. But this is the one to whom I will look: he who is humble and contrite in spirit and trembles at my word.
And without faith it is impossible to please him, for whoever would draw near to God must believe that he exists and that he rewards those who seek him.
So we see that they were unable to enter because of unbelief.
And blessed is the one who is not offended by me.
2 Corinthians 6:14-18
Do not be unequally yoked with unbelievers. For what partnership has righteousness with lawlessness? Or what fellowship has light with darkness? What accord has Christ with Belial? Or what portion does a believer share with an unbeliever? What agreement has the temple of God with idols? For we are the temple of the living God; as God said, “I will make my dwelling among them and walk among them, and I will be their God, and they shall be my people. Therefore go out from their midst, and be separate from them, says the Lord, and touch no unclean thing; then I will welcome you, and I will be a father to you, and you shall be sons and daughters to me, says the Lord Almighty.”
Whoever believes in the Son has eternal life; whoever does not obey the Son shall not see life, but the wrath of God remains on him.
