Hebrews 4:1-11

Therefore, while the promise of entering his rest still stands, let us fear lest any of you should seem to have failed to reach it. For good news came to us just as to them, but the message they heard did not benefit them, because they were not united by faith with those who listened. For we who have believed enter that rest, as he has said,
“As I swore in my wrath,
‘They shall not enter my rest,'”
although his works were finished from the foundation of the world. For he has somewhere spoken of the seventh day in this way: “And God rested on the seventh day from all his works.” And again in this passage he said,
“They shall not enter my rest.”
Since therefore it remains for some to enter it, and those who formerly received the good news failed to enter because of disobedience, again he appoints a certain day, “Today,” saying through David so long afterward, in the words already quoted,
“Today, if you hear his voice,
do not harden your hearts.”
For if Joshua had given them rest, God would not have spoken of another day later on. So then, there remains a Sabbath rest for the people of God, 10 for whoever has entered God’s rest has also rested from his works as God did from his.
11 Let us therefore strive to enter that rest, so that no one may fall by the same sort of disobedience. 
Hebrews 4:1-11 (ESV)

Hebrews 3:6-19

 but Christ is faithful over God’s house as a son. And we are his house, if indeed we hold fast our confidence and our boasting in our hope.

Therefore, as the Holy Spirit says,

“Today, if you hear his voice,
8 do not harden your hearts as in the rebellion,
on the day of testing in the wilderness,
9 where your fathers put me to the test
and saw my works for forty years.
10 Therefore I was provoked with that generation,
and said, ‘They always go astray in their heart;
they have not known my ways.’
11 As I swore in my wrath,
‘They shall not enter my rest.'”
12 Take care, brothers, lest there be in any of you an evil, unbelieving heart, leading you to fall away from the living God. 13 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. 14 For we have come to share in Christ, if indeed we hold our original confidence firm to the end. 15 As it is said,
“Today, if you hear his voice,
do not harden your hearts as in the rebellion.”
16 For who were those who heard and yet rebelled? Was it not all those who left Egypt led by Moses? 17 And with whom was he provoked for forty years? Was it not with those who sinned, whose bodies fell in the wilderness? 18 And to whom did he swear that they would not enter his rest, but to those who were disobedient? 19 So we see that they were unable to enter because of unbelief.
Hebrews 3:6-19 (ESV)

Hebrews 2:1-3

Therefore we must pay much closer attention to what we have heard, lest we drift away from it. For since the message declared by angels proved to be reliable, and every transgression or disobedience received a just retribution, how shall we escape if we neglect such a great salvation? It was declared at first by the Lord, and it was attested to us by those who heard,
Hebrews 2:1-3 (ESV)


Titus 1:15-16

To the pure, all things are pure, but to the defiled and unbelieving, nothing is pure; but both their minds and their consciences are defiled. 16 They profess to know God, but they deny him by their works. They are detestable, disobedient, unfit for any good work.
Titus 1:15-16 (ESV)


1 Timothy 6:3-10

If anyone teaches a different doctrine and does not agree with the sound words of our Lord Jesus Christ and the teaching that accords with godliness, he is puffed up with conceit and understands nothing. He has an unhealthy craving for controversy and for quarrels about words, which produce envy, dissension, slander, evil suspicions, and constant friction among people who are depraved in mind and deprived of the truth, imagining that godliness is a means of gain. But godliness with contentment is great gain, for we brought nothing into the world, and we cannot take anything out of the world. But if we have food and clothing, with these we will be content. But those who desire to be rich fall into temptation, into a snare, into many senseless and harmful desires that plunge people into ruin and destruction. 10 For the love of money is a root of all kinds of evils. It is through this craving that some have wandered away from the faith and pierced themselves with many pangs.
1 Timothy 6:3-10 (ESV)


1 Timothy 5:5-15

She who is truly a widow, left all alone, has set her hope on God and continues in supplications and prayers night and day, but she who is self-indulgent is dead even while she lives. Command these things as well, so that they may be without reproach. But if anyone does not provide for his relatives, and especially for members of his household, he has denied the faith and is worse than an unbeliever.
Let a widow be enrolled if she is not less than sixty years of age, having been the wife of one husband, 10 and having a reputation for good works: if she has brought up children, has shown hospitality, has washed the feet of the saints, has cared for the afflicted, and has devoted herself to every good work. 11 But refuse to enroll younger widows, for when their passions draw them away from Christ, they desire to marry 12 and so incur condemnation for having abandoned their former faith. 13 Besides that, they learn to be idlers, going about from house to house, and not only idlers, but also gossips and busybodies, saying what they should not. 14 So I would have younger widows marry, bear children, manage their households, and give the adversary no occasion for slander. 15 For some have already strayed after Satan.
