16 verses:
MT 10:22, “All men will hate you because of me, but he who stands firm to the end will be saved.”
RM 11:22, “Consider therefore the kindness and sternness of God: sternness to those who fell, but kindness to you, provided that you continue in his kindness. Otherwise, you also will be cut off.”
1CR 15:2, “By this gospel you are saved, if you hold firmly to the word I preached to you. Otherwise, you have believed in vain.”
GL 5:4, “You who are trying to be justified by law have been alienated from Christ; you have fallen away from grace.”
CL 1:22-23, “But now he has reconciled you by Christ’s physical body through death to present you holy in his sight, without blemish and free from accusation—if you continue in your faith, established and firm, not moved from the hope held out in the gospel.”
2THS 1:4-5, “Therefore, among God’s churches we boast about your perseverance and faith in all the persecutions and trials you are enduring. All this is evidence that God’s judgment is right, and as a result you will be counted worthy of the kingdom of God, for which you are suffering.”
2TM 2:12, “If we endure, we will also reign with him. If we disown him, he will also disown us;”
HB 3:6&14, “But Christ is faithful as a son over God’s house. And we are his house, if we hold on to our courage and the hope of which we boast… We have come to share in Christ if we hold firmly till the end the confidence we had at first.”
HB 6:4-6, “It is impossible for those who have once been enlightened, who have tasted the heavenly gift, who have shared in the Holy Spirit, who have tasted the goodness of the word of God and the powers of the coming age, if they fall away, to be brought back to repentance, because to their loss they are crucifying the Son of God all over again and subjecting him to public disgrace.” This passage indicates that apostasy may be viewed as total depravity or blasphemy against the HS (MT 12:31).
HB 10:26-36, “If we deliberately keep on sinning after we have received the knowledge of the truth, no sacrifice for sins is left, but only a fearful expectation of judgment and of raging fire that will consume the enemies of God… So do not throw away your confidence; it will be richly rewarded. You need to persevere so that when you have done the will of God, you will receive what he has promised.”
JM 1:12, “Blessed is the man who perseveres under trial, because when he has stood the test, he will receive the crown of life that God has promised to those who love him.”

2PT 2:20, “If they have escaped the corruption of the world by knowing our Lord and Savior Jesus Christ and are again entangled in it and overcome, they are worse off at the end than they were at the beginning.”
1JN 2:24-25, “See that what you have heard from the beginning remains in you. If it does, you also will remain in the Son and in the Father. And this is what he promised us—even eternal life.”
JUDE 21, “Keep yourselves in God’s love as you wait for the mercy of our Lord Jesus Christ to bring you to eternal life.”
RV 2:10, “Do not be afraid of what you are about to suffer. I tell you, the devil will put some of you in prison to test you, and you will suffer persecution for ten days. Be faithful, even to the point of death, and I will give you the crown of life.”
and let us consider one another to provoke unto love and to good works: not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching.
