Be Polite in Speech and Behavior
Many Christians are rude in their speech and behavior without even noticing it themselves. Because they overlook it, they did not change. When you speak, you should avoid using vulgar words. Usually, people scold vulgar words when they are angry or frustrated or want to mock something. It is also wrong to misuse God’s name as a habit. For example, some people like to say the name Jesus Christ! or go to Hell and etc. In Exodus 20:7, thou shalt not take the name of the LORD thy God in vain; for the LORD will not hold him guiltless that taketh his name in vain.
The most important commandment of God is to love one another as you love yourself (Matthew 22:36-40). If you love others, the words that come out of your mouth will always be gentle and polite. What you say with your mouth reflect your feelings and thoughts. In Matthew 15:18, but those things which proceed out of the mouth come forth from the heart; and they defile the man. In 1 Corinthians 13:4-7, charity suffereth long, and is kind; charity envieth not; charity vaunteth not itself, is not puffed up, Doth not behave itself unseemly, seeketh not her own, is not easily provoked, thinketh no evil; Rejoiceth not in iniquity, but rejoiceth in the truth; Beareth all things, believeth all things, hopeth all things, endureth all things.
One of the fruits of the Holy Spirit is gentle (Galatians 5:21-22). We must be polite and gentle in our speech, and behavior. If you used to be rude and rough with people, you should ask God to change your bad habit. Some people are naturally rude in speaking to people and handling things. For example, some people would rather shout at people than to speak gently. If you have a habit of being rude with people and handling things, you can ask the Holy Spirit to help you. You must nail your old self, the wrong way you use to do things, to the cross and let the Lord Jesus Christ completely take in charge of you so that you can be more and more like Jesus Christ.
If you saw someone sin, you must rebuke him in a spirit of gentleness. In Galatians 6:1, Brethren, if a man be overtaken in a fault, ye which are spiritual, restore such an one in the spirit of meekness; considering thyself, lest thou also be tempted. We must not be proud but be polite, gentle and kind to those in the lower social position. In Romans 12:16, be of the same mind one toward another. Mind not high things, but condescend to men of low estate. Be not wise in your own conceits.
Respect the Government Authorities
We must submit to the government authorities because they carry out God’s commandment. The laws of the government were established to punish criminals who sin against God. The government will only sentence a punishment on a person who do a crime and not on the innocent. Therefore, we must submit to the authorities not just because of possible punishment but also of conscience (Romans 13:1-5). However, if the government law oppose what is taught in the bible, you should not obey it. In Titus 3:1, put them in mind to be subject to principalities and powers, to obey magistrates, to be ready to every good work, To speak evil of no man, to be no brawlers, but gentle, shewing all meekness unto all men.
Be Polite to the Elders
Many Christians are rude to the elders. Children must respect their parents and speak to them politely. Children should obey their parents’ decisions and never talk back against them. In Ephesians 6:1-3, children, obey your parents in the Lord: for this is right. Honour thy father and mother; (which is the first commandment with promise;) That it may be well with thee, and thou mayest live long on the earth. In Colossians 3:20, children, obey your parents in all things: for this is well pleasing unto the Lord. In Proverbs 1:8, my son, hear the instruction of thy father, and forsake not the law of thy mother.
We must respect the elders and rebuke them as a father. In Leviticus 19:32, thou shalt rise up before the hoary head, and honour the face of the old man, and fear thy God: I am the LORD. In Proverbs 20:29, the glory of young men is their strength: and the beauty of old men is the gray head. In 1 Timothy 5:1, rebuke not an elder, but intreat him as a father; and the younger men as brethren.
We must respect the leaders in the church and be polite to them. In Hebrews 13:17, obey them that have the rule over you, and submit yourselves: for they watch for your souls, as they that must give account, that they may do it with joy, and not with grief: for that is unprofitable for you. In 1 Thessalonians 5:12, and we beseech you, brethren, to know them which labour among you, and are over you in the Lord, and admonish you.
