WHAT IS A FALSE CHRISTIAN?

They will act religious, but they will reject the power that could make them godly. Stay away from people like that!
II Timothy 3:5 (NLT)

Everything is pure to those whose hearts are pure. But nothing is pure to those who are corrupt and unbelieving, because their minds and consciences are corrupted.
Titus 1:15 (NLT)

Such people clam they know God, but they deny Him by the way they live. They are detestable and disobedient, worthless for doing anything good.
Titus 1:16 (NLT)

‘These people honor Me with their lips, but their hearts are far from Me.’
Matthew 15:8 (NLT)

And I’m not changing my position on this. I’d die before taking your money. I’m giving nobody grounds for lumping me in with those money-grubbing “preachers,” vaunting themselves as something special. They’re a sorry bunch, pseudo-apostles, lying preachers, crooked workers, posing as Christ’s agents but sham to the core. And no wonder! satan does it all the time, dressing up as a beautiful angel of light. So it shouldn’t surprise us when his servants masquerade as servants of God. But they’re not getting by with anything. They’ll pay for it in the end.
II Corinthians 11:12-15 (MSG)

Someone may say, “I am a Christian; I am on my way to heaven; I belong to Christ.” But if he doesn’t do what Christ tells him to, he is a liar.
I John 2:4 (TLB)

If anyone claims, “I am living in the light,” but hates a fellow believer, that person is still living in darkness.
I John 2:9 (NLT)

So if we stay close to Him, obedient to Him, we won’t be sinning either; but as for those who keep on sinning, they should realize this: They sin because they have never really known Him or become His.
I John 3:6 (TLB)

Oh, dear children, don’t let anyone deceive you about this: if you are constantly doing what is good, it is because you are good, even as He is. But if you keep on sinning, it shows that you belong to satan, who since he first began to sin has kept steadily at it. But The Son of God came to destroy these works of the devil. The person who has been born into God’s family does not make a practice of sinning because now God’s Life is in him; so he can’t keep on sinning, for this new life has been born into him and controls him, he has been born again.
I John 3:7-9 (TLB)

So now we can tell who is a child of God and who belongs to satan. Whoever is living a life of sin and doesn’t love his brother shows that he is not in God’s family; for the message to us from the beginning has been that we should love one another.
I John 3:10-11 (TLB)

“Not all who sound religious are really godly people. They may refer to Me as ‘Lord,’ but still won’t get to heaven. For the decisive question is whether they obey My Father in heaven.
Matthew 7:21 (TLB)

At the Judgement, many will tell Me, ‘Lord, Lord, we told others about You and used Your Name to cast out demons and to do many other great miracles.’ But I will reply, ‘You have never been Mine. Go away, for your deeds are evil.’
Matthew 7:22-23 (TLB)

Therefore if anyone is in Christ, (that is, grafted in, joined to Him by faith in Him as Savior), he is a new creature (reborn and renewed by The Holy Spirit); the old things (the previous moral and spiritual condition) have passed away. Behold, new things have come because spiritual awakening brings a new life.
II Corinthians 5:17 (AMP)
