It is good that we be reminded of these Safe Guards:
II Thessalonians 3:6 (Focus)
6 But we command you, brethren, in the name of our Lord Jesus Christ, that you withdraw from every brother who walks disorderly and not according to the tradition which he received from us. 7 For you yourselves know how you ought to follow us, for we were not disorderly among you; 8 nor did we eat anyone’s bread free of charge, but worked with labor and toil night and day, that we might not be a burden to any of you, 9 not because we do not have authority, but to make ourselves an example of how you should follow us.
10 For even when we were with you, we commanded you this: If anyone will not work, neither shall he eat. 11 For we hear that there are some who walk among you in a disorderly manner, not working at all, but are busybodies. 12 Now those who are such we command and exhort through our Lord Jesus Christ that they work in quietness and eat their own bread.
13 But as for you, brethren, do not grow weary in doing good. 14 And if anyone does not obey our word in this epistle, note that person and do not keep company with him, that he may be ashamed. 15 Yet do not count him as an enemy, but admonish him as a brother.
Acts 20:28-29 (Focus)
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.
32 “So now, brethren, I commend you to God and to the word of His grace, which is able to build you up and give you an inheritance among all those who are sanctified. 33 I have coveted no one’s silver or gold or apparel. 34 Yes, you yourselves know that these hands have provided for my necessities, and for those who were with me. 35 I have shown you in every way, by laboring like this, that you must support the weak. And remember the words of the Lord Jesus, that He said, ‘It is more blessed to give than to receive.’ ”
Romans 16:17-18 (Focus)
17 Now I urge you, brethren, note those who cause divisions and offenses, contrary to the doctrine which you learned, and avoid them. 18 For those who are such do not serve our Lord Jesus Christ, but their own belly, and by smooth words and flattering speech deceive the hearts of the simple. 19 For your obedience has become known to all. Therefore I am glad on your behalf; but I want you to be wise in what is good, and simple concerning evil. 20 And the God of peace will crush Satan under your feet shortly.
The grace of our Lord Jesus Christ be with you. Amen.
1 Timothy 6:5 (Focus)
3 If anyone teaches otherwise and does not consent to wholesome words, even the words of our Lord Jesus Christ, and to the doctrine which accords with godliness, 4 he is proud, knowing nothing, but is obsessed with disputes and arguments over words, from which come envy, strife, reviling, evil suspicions, 5 useless wranglings of men of corrupt minds and destitute of the truth, who suppose that godliness is a means of gain. From such withdraw yourself.
2 Timothy 3:5 (Focus)
3 But know this, that in the last days perilous times will come: 2 For men will be lovers of themselves, lovers of money, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy, 3 unloving, unforgiving, slanderers, without self-control, brutal, despisers of good, 4 traitors, headstrong, haughty, lovers of pleasure rather than lovers of God, 5 having a form of godliness but denying its power. And from such people turn away!
1 Corinthians 11:1-2 (Focus)
Imitate me, just as I also imitate Christ. 2 Now I praise you, brethren, that you remember me in all things and keep the traditions just as I delivered them to you.
2 John 9-11 (Focus)
9 Anyone who wanders away from this teaching has no relationship with God. But anyone who remains in the teaching of Christ has a relationship with both the Father and the Son.
10 If anyone comes to your meeting and does not teach the truth about Christ, don’t invite that person into your home or give any kind of encouragement. 11 Anyone who encourages such people becomes a partner in their evil work.
Here’s another one 2 John 9-11 | 9 Anyone who wanders away from this teaching has no relationship with God.
