Matthew 24:10-13
And then many will fall away and betray one another and hate one another. And many false prophets will arise and lead many astray. And because lawlessness will be increased, the love of many will grow cold. But the one who endures to the end will be saved.
2 Peter 2:20-22
For if, after they have escaped the defilements of the world through the knowledge of our Lord and Savior Jesus Christ, they are again entangled in them and overcome, the last state has become worse for them than the first. For it would have been better for them never to have known the way of righteousness than after knowing it to turn back from the holy commandment delivered to them. What the true proverb says has happened to them: “The dog returns to its own vomit, and the sow, after washing herself, returns to wallow in the mire.”
Hebrews 6:4-6
For it is impossible, in the case of those who have once been enlightened, who have tasted the heavenly gift, and have shared in the Holy Spirit, and have tasted the goodness of the word of God and the powers of the age to come, and then have fallen away, to restore them again to repentance, since they are crucifying once again the Son of God to their own harm and holding him up to contempt.
Hebrews 3:12-14
Take care, brothers, lest there be in any of you an evil, unbelieving heart, leading you to fall away from the living God. But exhort one another every day, as long as it is called “today,” that none of you may be hardened by the deceitfulness of sin. For we have come to share in Christ, if indeed we hold our original confidence firm to the end.
Romans 11:19-22
Then you will say, “Branches were broken off so that I might be grafted in.” That is true. They were broken off because of their unbelief, but you stand fast through faith. So do not become proud, but fear. For if God did not spare the natural branches, neither will he spare you. Note then the kindness and the severity of God: severity toward those who have fallen, but God's kindness to you, provided you continue in his kindness. Otherwise you too will be cut off.
Colossians 1:22-23
In the body of His flesh through death, to present you holy, and blameless, and above reproach in His sight— if indeed you continue in the faith, grounded and steadfast, and are not moved away from the hope of the gospel which you heard, which was preached to every creature under heaven, of which I, Paul, became a minister.
Romans 2:6-10
Who will render to every man according to his deeds:
To them who by patient continuance in well doing seek for glory and honour and immortality, eternal life:
But unto them that are contentious, and do not obey the truth, but obey unrighteousness, indignation and wrath,
Tribulation and anguish, upon every soul of man that doeth evil, of the Jew first, and also of the Gentile;
But glory, honour, and peace, to every man that worketh good, to the Jew first, and also to the Gentile:
Acts 20:28-31
28 Therefore take heed to yourselves and to all the flock, among which the Holy Spirit has made you overseers, to shepherd the church of God which He purchased with His own blood. 29 For I know this, that after my departure savage wolves will come in among you, not sparing the flock. 30 Also from among yourselves men will rise up, speaking perverse things, to draw away the disciples after themselves. 31 Therefore watch, and remember that for three years I did not cease to warn everyone night and day with tears.
1 Timothy 4:1
Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils;
[h=1]James 5:19-20[/h]19 My brothers and sisters, if one of you should wander from the Truth and someone should bring that person back, 20 remember this: Whoever turns a sinner from the error of their way will save them from death and cover over a multitude of sins.
