Ephesians 4:32 KJV
And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ’s sake hath forgiven you.
Ephesians 4:29 KJV
Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.
Philippians 2:1-4 KJV
If there be therefore any consolation in Christ, if any comfort of love, if any fellowship of the Spirit, if any bowels and mercies, Fulfil ye my joy, that ye be likeminded, having the same love, being of one accord, of one mind. Let nothing be done through strife or vainglory; but in lowliness of mind let each esteem other better than themselves. Look not every man on his own things, but every man also on the things of others.
Romans 12:19 KJV
Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord.
Matthew 5:43-48 KJV
Ye have heard that it hath been said, Thou shalt love thy neighbour, and hate thine enemy. But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you; That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust. For if ye love them which love you, what reward have ye? do not even the publicans the same? And if ye salute your brethren only, what do ye more than others? do not even the publicans so? Be ye therefore perfect, even as your Father which is in heaven is perfect.
Colossians 4:6 KJV
Let your speech be alway with grace, seasoned with salt, that ye may know how ye ought to answer every man.
1 Corinthians 8:6 KJV
But to us there is but one God, the Father, of whom are all things, and we in him; and one Lord Jesus Christ, by whom are all things, and we by him.
Matthew 7:12 KJV
Therefore all things whatsoever ye would that men should do to you, do ye even so to them: for this is the law and the prophets.
Galatians 6:1-18 KJV
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. Bear ye one another’s burdens, and so fulfil the law of Christ. For if a man think himself to be something, when he is nothing, he deceiveth himself. But let every man prove his own work, and then shall he have rejoicing in himself alone, and not in another. For every man shall bear his own burden. Let him that is taught in the word communicate unto him that teacheth in all good things. Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap. For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting. And let us not be weary in well doing: for in due season we shall reap, if we faint not. As we have therefore opportunity, let us do good unto all men, especially unto them who are of the household of faith. Ye see how large a letter I have written unto you with mine own hand. As many as desire to make a fair shew in the flesh, they constrain you to be circumcised; only lest they should suffer persecution for the cross of Christ. For neither they themselves who are circumcised keep the law; but desire to have you circumcised, that they may glory in your flesh. But God forbid that I should glory, save in the cross of our Lord Jesus Christ, by whom the world is crucified unto me, and I unto the world. For in Christ Jesus neither circumcision availeth any thing, nor uncircumcision, but a new creature. And as many as walk according to this rule, peace be on them, and mercy, and upon the Israel of God. From henceforth let no man trouble me: for I bear in my body the marks of the Lord Jesus. Brethren, the grace of our Lord Jesus Christ be with your spirit. Amen.
Proverbs 25:13-23 KJV
As the cold of snow in the time of harvest, so is a faithful messenger to them that send him: for he refresheth the soul of his masters. Whoso boasteth himself of a false gift is like clouds and wind without rain. By long forbearing is a prince persuaded, and a soft tongue breaketh the bone. Hast thou found honey? eat so much as is sufficient for thee, lest thou be filled therewith, and vomit it. Withdraw thy foot from thy neighbour’s house; lest he be weary of thee, and so hate thee. A man that beareth false witness against his neighbour is a maul, and a sword, and a sharp arrow. Confidence in an unfaithful man in time of trouble is like a broken tooth, and a foot out of joint. As he that taketh away a garment in cold weather, and as vinegar upon nitre, so is he that singeth songs to an heavy heart.
If thine enemy be hungry, give him bread to eat; and if he be thirsty, give him water to drink: For thou shalt heap coals of fire upon his head, and the LORD shall reward thee. The north wind driveth away rain: so doth an angry countenance a backbiting tongue.
Psalms 141:5 KJV
Let the righteous smite me; it shall be a kindness: and let him reprove me; it shall be an excellent oil, which shall not break my head: for yet my prayer also shall be in their calamities.
1 Corinthians 13:4 KJV
Charity suffereth long, and is kind; charity envieth not; charity vaunteth not itself, is not puffed up,
Ecclesiastes 7:16-18 KJV
Be not righteous over much; neither make thyself over wise: why shouldest thou destroy thyself? Be not over much wicked, neither be thou foolish: why shouldest thou die before thy time? It is good that thou shouldest take hold of this; yea, also from this withdraw not thine hand: for he that feareth God shall come forth of them all.
Matthew 7:7 KJV
Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you:
