Titus 1:10 For there are many unruly and vain talkers and deceivers, specially they of the circumcision:
unruly; not under submission to authority
vain talkers; speaking empty worthless words
deceivers; seducers, seeking to take advantage of you
the circumcision; the old covenant Jews, those who do not understand nor receive the grace of Jesus, or those who wish to put Jewish customs upon the Christians. For example, insisting in circumcision.
Gal 5:10 I have confidence in you through the Lord, that ye will be none otherwise minded: but he that troubleth you shall bear his judgment, whosoever he be.
Gal 5:11 And I, brethren, if I yet preach circumcision, why do I yet suffer persecution? then is the offence of the cross ceased.
Gal 5:12 I would they were even cut off which trouble you.
Gal 5:13 For, brethren, ye have been called unto liberty; only use not liberty for an occasion to the flesh, but by love serve one another.
Titus 1:11 Whose mouths must be stopped, who subvert whole houses, teaching things which they ought not, for filthy lucre's sake.
These dangerous false teachers must be exposed and stopped, they are seeking your money. They want to use you and are dangerous to follow, for they are not of God.
Titus 1:12 One of themselves, even a prophet of their own, said, The Cretians are alway liars, evil beasts, slow bellies.
False prophets speaking words to condemn others, making destructive prophecies to destroy those they do not favor. Assuming to speak from God, they speak harm and destruction. A prophet is not to speak false words. Some want the title and speak words of a soon coming event and are false. Avoid them. Prophecy is not of a man or woman, but of God.
One of their false prophets was a racist, placing lies and curses in the place of truth. Be careful in your use of the word "all." Unless, God says it, it probably isn't so. Hitler used racism, calling the Jews vermin, so that this lie led to the extermination of millions of God's covenant people.
God said this:
Rom 3:23 For all have sinned, and come short of the glory of God;
Rom 3:24 Being justified freely by his grace through the redemption that is in Christ Jesus:
God's "all," provides grace with it. He gives us a way to escape. Jesus came to save, not to destroy with words, but with words of grace. Beware of anyone who claims to speak for God who curses, without giving a way to escape. We speak words of life and truth.
1 Cor 10:13 There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it.
There are true prophets and false prophets
2 Pet 1:21 For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost.
2 Pet 2:1 But there were false prophets also among the people, even as there shall be false teachers among you, who privily shall bring in damnable heresies, even denying the Lord that bought them, and bring upon themselves swift destruction.
2 Pet 2:2 And many shall follow their pernicious ways; by reason of whom the way of truth shall be evil spoken of.
2 Pet 2:3 And through covetousness shall they with feigned words make merchandise of you: whose judgment now of a long time lingereth not, and their damnation slumbereth not.
Titus 1:13 This witness is true. Wherefore rebuke them sharply, that they may be sound in the faith;
Rebuke them sharply, this is serious, convict them of their wrong doing with a strong rebuke, it is not something to be ignored. Speak to them, not by your thoughts or feelings, but by God's sound word, restore them with sound doctrine and restore them in the faith having repented of their sins.
Titus 1:14 Not giving heed to Jewish fables, and commandments of men, that turn from the truth.
The Jews had many regulations and ordinances that were made up by men. We are not to be under the bondage of men's words or presumptions.
Col 2:13 And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses;
Col 2:14 Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;
We are not under their rules, but under Christ and his blood, free to serve him with cleansed hearts, through the Holy Spirit. Any witness for Christ will be confronted by mockers, but we must remain in the sound word of God's truth.
Titus 1:15 Unto the pure all things are pure: but unto them that are defiled and unbelieving is nothing pure; but even their mind and conscience is defiled.
How true, to the pure of heart, all things they do and say are pure. But, to those who are defiled by sin and unbelief, nothing is pure, not even their conscience. They have no frame of reference, no absolutes, all is wicked imaginations. They need prayer so that God will soften their unbelieving hearts to the acknowledgment of Jesus Christ. Restoration is in Jesus.
Titus 1:16 They profess that they know God; but in works they deny him, being abominable, and disobedient, and unto every good work reprobate.
They profess a God of their making, not showing a change in their behavior. In their lifestyle they deny him. They are:
abominable; detestable, disgusting in behavior, most unpleasant to be around them.
disobedient, self willed, not under authority of man or God. They refuse to obey that which is good and true.
reprobate; morally corrupt, despising that which is good, depraved.
And yet, they profess to know God.
Mat 3:9 And think not to say within yourselves, We have Abraham to our father: for I say unto you, that God is able of these stones to raise up children unto Abraham.
Mat 3:10 And now also the ax is laid unto the root of the trees: therefore every tree which bringeth not forth good fruit is hewn down, and cast into the fire.
Mat 7:15 Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.
Mat 7:16 Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?
Mat 7:17 Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit.
Mat 7:18 A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit.
Mat 7:19 Every tree that bringeth not forth good fruit is hewn down, and cast into the fire.
Mat 7:20 Wherefore by their fruits ye shall know them.
Mat 7:21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
Mat 7:22 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
Mat 7:23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
We are to attempt to restore them by strong rebuke and the truth of God. God must change them, we must witness, motivated by love and pray for them.
