1 Corinthians 10: 5 Nevertheless, God was not pleased with most of them; their bodies were scattered over the desert. (6) Now these things occurred as examples to keep us from setting our hearts on evil things as they did. (7) Do not be idolaters, as some of them were; as it is written: "The people sat down to eat and drink and got up to indulge in pagan revelry." (8) We should not commit sexual immorality, as some of them did-- and in one day twenty-three thousand of them died. (9) We should not test the Lord, as some of them did-- and were killed by snakes. (10) And do not grumble, as some of them did-- and were killed by the destroying angel. (11) These things happened to them as examples and were written down as warnings for us, on whom the fulfillment of the ages has come. (12) So, if you think you are standing firm, be careful that you don't fall!
1 Peter 1:17 Since you call on a Father who judges each man's work impartially, live your lives as strangers here in reverent fear.
Acts 5: 3 Then Peter said, Ananias, how is it that Satan has so filled your heart that you have lied to the Holy Spirit and have kept for yourself some of the money you received for the land? . . . (5) When Ananias heard this, he fell down and died. And great fear seized all who heard what had happened
Hebrews 10:26 If we deliberately keep on sinning after we have received the knowledge of the truth, no sacrifice for sins is left, (27) but only a fearful expectation of judgment and of raging fire that will consume the enemies of God. (28) Anyone who rejected the law of Moses died without mercy on the testimony of two or three witnesses. (29) How much more severely do you think a man deserves to be punished who has trampled the Son of God under foot, who has treated as an unholy thing the blood of the covenant that sanctified him, and who has insulted the Spirit of grace? (30) For we know him who said, It is mine to avenge; I will repay, and again, The Lord will judge his people. (31) It is a dreadful thing to fall into the hands of the living God.
