Deuteronomy 4:9

9 aOnly take care, and bkeep your soul diligently, lest you forget the things that your eyes have seen, and lest they depart from your heart all the days of your life. cMake them known to your children and your children’s children

Proverbs 4:23

23Keep your heart with all vigilance,
for dfrom it flow ethe springs of life.

1 Corinthians 9:24-27

24Do you not know that in a race all the runners run, but only one receives fthe prize? So grun that you may obtain it. 25Every hathlete exercises self-control in all things. They do it to receive a perishable wreath, but we ian imperishable. 26So I do not run aimlessly; I jdo not box as one kbeating the air. 27But I discipline my body and lkeep it under control,
Greek  I pummel my body and make it a slave
lest after preaching to others nI myself should be odisqualified.

Hebrews 2:1-2

Warning Against Neglecting Salvation

1Therefore we must pay much closer attention to what we have heard, lest we drift away from it. 2For since pthe message declared by angels proved to be reliable, and qevery transgression or disobedience received a just rretribution,

Hebrews 3:12

12Take care, brothers, lest there be in any of you an evil, unbelieving heart, leading you to fall away from sthe living God.

Hebrews 4:1

1Therefore, while the promise of entering his rest still stands, let us fear lest any of you should seem tto have failed to reach it.

Hebrews 4:11

11Let us therefore strive to enter that rest, so uthat no one may fall by the same sort of disobedience.

Hebrews 6:11

11And we desire each one of you to show the same earnestness to have the full assurance vof hope until the end,

Hebrews 10:23-35

23 wLet us hold fast the confession of our hope without wavering, for xhe who promised is faithful. 24And ylet us consider how to stir up one another to love and good works, 25 znot neglecting to meet together, as is the habit of some, but encouraging one another, and aaall the more as you see abthe Day drawing near.

26For acif we go on sinning deliberately adafter receiving the knowledge of the truth, aethere no longer remains a sacrifice for sins, 27 afbut a fearful expectation of judgment, and aga fury of fire that will consume the adversaries. 28 ahAnyone who has set aside the law of Moses dies without mercy aion the evidence of two or three witnesses. 29How much worse punishment, do you think, will be deserved by the one ajwho has trampled underfoot the Son of God, and has profaned akthe blood of the covenant alby which he was sanctified, and has amoutraged the Spirit of grace? 30For we know him who said, anVengeance is mine; I will repay.” And again, ao“The Lord will judge his people.” 31 apIt is a fearful thing to fall into the hands of the living God.

32But recall the former days when, after aqyou were enlightened, you endured ara hard struggle with sufferings, 33sometimes being aspublicly exposed to reproach and affliction, and sometimes being partners with those so treated. 34For atyou had compassion on those in prison, and auyou joyfully accepted the plundering of your property, since you knew that you yourselves had ava better possession and an abiding one. 35Therefore do not throw away your confidence, which has awa great reward.
