How do you offer correction?

Acts 24:16
16So I strive always to keep my conscience clear before God and man.

Rom 2:15
12All who sin apart from the law will also perish apart from the law, and all who sin under the law will be judged by the law. 13For it is not those who hear the law who are righteous in God's sight, but it is those who obey the law who will be declared righteous. 14(Indeed, when Gentiles, who do not have the law, do by nature things required by the law, they are a law for themselves, even though they do not have the law, 15since they show that the requirements of the law are written on their hearts, their consciences also bearing witness, and their thoughts now accusing, now even defending them.) 16This will take place on the day when God will judge men's secrets through Jesus Christ, as my gospel declares.

Rom 9:1
1I speak the truth in Christ—I am not lying, my conscience confirms it in the Holy Spirit— 2I have great sorrow and unceasing anguish in my heart. 3For I could wish that I myself were cursed and cut off from Christ for the sake of my brothers, those of my own race, 4the people of Israel. Theirs is the adoption as sons; theirs the divine glory, the covenants, the receiving of the law, the temple worship and the promises. 5Theirs are the patriarchs, and from them is traced the human ancestry of Christ, who is God over all, forever praised! Amen.

Rom 14:2
1Accept him whose faith is weak, without passing judgment on disputable matters. 2One man's faith allows him to eat everything, but another man, whose faith is weak, eats only vegetables. 3The man who eats everything must not look down on him who does not, and the man who does not eat everything must not condemn the man who does, for God has accepted him. 4Who are you to judge someone else's servant? To his own master he stands or falls. And he will stand, for the Lord is able to make him stand.

1Cor 4:4
1So then, men ought to regard us as servants of Christ and as those entrusted with the secret things of God. 2Now it is required that those who have been given a trust must prove faithful. 3I care very little if I am judged by you or by any human court; indeed, I do not even judge myself. 4My conscience is clear, but that does not make me innocent. It is the Lord who judges me. 5Therefore judge nothing before the appointed time; wait till the Lord comes. He will bring to light what is hidden in darkness and will expose the motives of men's hearts. At that time each will receive his praise from God.

1Tim 1:5
3As I urged you when I went into Macedonia, stay there in Ephesus so that you may command certain men not to teach false doctrines any longer 4nor to devote themselves to myths and endless genealogies. These promote controversies rather than God's work—which is by faith. 5The goal of this command is love, which comes from a pure heart and a good conscience and a sincere faith. 6Some have wandered away from these and turned to meaningless talk. 7They want to be teachers of the law, but they do not know what they are talking about or what they so confidently affirm.

1Tim 3:9
8Deacons, likewise, are to be men worthy of respect, sincere, not indulging in much wine, and not pursuing dishonest gain. 9They must keep hold of the deep truths of the faith with a clear conscience. 10They must first be tested; and then if there is nothing against them, let them serve as deacons.

1Tim 4:2
1The Spirit makes it clear that as time goes on, some are going to give up on the faith and chase after demonic illusions put forth by professional liars. 2These liars have lied so well and for so long that they've lost their capacity for truth. 3They will tell you not to get married. They'll tell you not to eat this or that food--perfectly good food God created to be eaten heartily and with thanksgiving by Christians! 4Everything God created is good, and to be received with thanks. Nothing is to be sneered at and thrown out. 5God's Word and our prayers make every item in creation holy.

1 Peter 2:19
13Submit yourselves for the Lord's sake to every authority instituted among men: whether to the king, as the supreme authority, 14or to governors, who are sent by him to punish those who do wrong and to commend those who do right. 15For it is God's will that by doing good you should silence the ignorant talk of foolish men. 16Live as free men, but do not use your freedom as a cover-up for evil; live as servants of God. 17Show proper respect to everyone: Love the brotherhood of believers, fear God, honor the king.

Titus 1:7
5The reason I left you in Crete was that you might straighten out what was left unfinished and appoint elders in every town, as I directed you. 6An elder must be blameless, the husband of but one wife, a man whose children believe and are not open to the charge of being wild and disobedient. 7Since an overseer is entrusted with God's work, he must be blameless—not overbearing, not quick-tempered, not given to drunkenness, not violent, not pursuing dishonest gain. 8Rather he must be hospitable, one who loves what is good, who is self-controlled, upright, holy and disciplined. 9He must hold firmly to the trustworthy message as it has been taught, so that he can encourage others by sound doctrine and refute those who oppose it.

Gal 5:16
16So I say, live by the Spirit, and you will not gratify the desires of the sinful nature. 17For the sinful nature desires what is contrary to the Spirit, and the Spirit what is contrary to the sinful nature. They are in conflict with each other, so that you do not do what you want. 18But if you are led by the Spirit, you are not under law.
