1 Thessalonians 5:4-28 KJV

[4] But ye, brethren, are not in darkness, that that day should overtake you as a thief. [5] Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness. [6] Therefore let us not sleep, as do others; but let us watch and be sober. [7] For they that sleep sleep in the night; and they that be drunken are drunken in the night. [8] But let us, who are of the day, be sober, putting on the breastplate of faith and love; and for an helmet, the hope of salvation. [9] For God hath not appointed us to wrath, but to obtain salvation by our Lord Jesus Christ, [10] Who died for us, that, whether we wake or sleep, we should live together with him. [11] Wherefore comfort yourselves together, and edify one another, even as also ye do. [12] And we beseech you, brethren, to know them which labour among you, and are over you in the Lord, and admonish you; [13] And to esteem them very highly in love for their work's sake. And be at peace among yourselves. [14] Now we exhort you, brethren, warn them that are unruly, comfort the feebleminded, support the weak, be patient toward all men. [15] See that none render evil for evil unto any man ; but ever follow that which is good, both among yourselves, and to all men. [16] Rejoice evermore. [17] Pray without ceasing. [18] In every thing give thanks: for this is the will of God in Christ Jesus concerning you. [19] Quench not the Spirit. [20] Despise not prophesyings. [21] Prove all things; hold fast that which is good. [22] Abstain from all appearance of evil. [23] And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ. [24] Faithful is he that calleth you, who also will do it. [25] Brethren, pray for us. [26] Greet all the brethren with an holy kiss. [27] I charge you by the Lord that this epistle be read unto all the holy brethren. [28] The grace of our Lord Jesus Christ be with you. Amen.

Proverbs 16:32 KJV

[32] He that is slow to anger is better than the mighty; and he that ruleth his spirit than he that taketh a city.

Philippians 4:13 KJV

[13] I can do all things through Christ which strengtheneth me.

Proverbs 12:16-28 KJV

[16] A fool's wrath is presently known: but a prudent man covereth shame. [17] He that speaketh truth sheweth forth righteousness: but a false witness deceit. [18] There is that speaketh like the piercings of a sword: but the tongue of the wise is health. [19] The lip of truth shall be established for ever: but a lying tongue is but for a moment. [20] Deceit is in the heart of them that imagine evil: but to the counsellors of peace is joy. [21] There shall no evil happen to the just: but the wicked shall be filled with mischief. [22] Lying lips are abomination to the Lord : but they that deal truly are his delight. [23] A prudent man concealeth knowledge: but the heart of fools proclaimeth foolishness. [24] The hand of the diligent shall bear rule: but the slothful shall be under tribute. [25] Heaviness in the heart of man maketh it stoop: but a good word maketh it glad. [26] The righteous is more excellent than his neighbour: but the way of the wicked seduceth them. [27] The slothful man roasteth not that which he took in hunting: but the substance of a diligent man is precious. [28] In the way of righteousness is life; and in the pathway thereof there is no death.

Proverbs 25:28 KJV

[28] He that hath no rule over his own spirit is like a city that is broken down, and without walls.

1 Corinthians 6:19-20 KJV

[19] What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? [20] For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God's.
