Should a Christian gamble or play the lotteries?

No. For every winner, there are always losers. In the case of lotteries there are sometimes hundreds of thousands or millions of losers for every few winners. The winner gets his gain by hurting others, even though the loser has chosen to put himself at risk.

God's Word teaches that we are to love others more than ourselves. When we do things that hurt others, we violate that principle. It is sin. Lest we think that no one is hurt by gambling, it would be enlightening to talk to professional counselors who have dealt with people who have gambling addictions. Ask about the wives, husbands, and children of gamblers. These are the real losers.

Our Bodies Belong To God
"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? For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God's" (1 Cor.6:19-20).

We Are Free In Christ, But We Should Take Care Not To Lead A Weaker Brother Astray When His Conscience Is Seared
"Howbeit there is not in every man that knowledge: for some with conscience of the idol unto this hour eat it as a thing offered unto an idol; and their conscience being weak is defiled. But meat commendeth us not to God: for neither, if we eat, are we the better; neither, if we eat not, are we the worse. But take heed lest by any means this liberty of your's become a stumbling block to them that are weak.For if any man see thee which hast knowledge sit at meat in the idol's temple, shall not the conscience of him which is weak be emboldened to eat those things which are offered to idols; And through thy knowledge shall the weak brother perish, for whom Christ died? But when ye sin so against the brethren, and wound their weak conscience, ye sin against Christ. Wherefore, if meat make my brother to offend, I will eat no flesh while the world standeth, lest I make my brother to offend" (1 Cor.8:7-13).

We Reflect His Glory
"But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord" (2 Cor. 3:18).

"For it is God which worketh in you both to will and to do of his good pleasure" (Phillipians 2:13).

We Are A New Creation"Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new" (2 Corinthians 5:17).

We Must Be Without Offense
"And this I pray, that your love may abound yet more and more in knowledge and in all judgment; That ye may approve things that are excellent; that ye may be sincere and without offence till the day of Christ. Being filled with the fruits of righteousness, which are by Jesus Christ, unto the glory and praise of God" (Phillipians 1:9-11).

"For we ourselves also were sometimes foolish, disobedient, deceived, serving divers lusts and pleasures, living in malice and envy, hateful, and hating one another" (Titus 3:3).

Seek/Set Your Affection On Those Things Which Are Above
"If ye then be risen with Christ, seek those things which are above, where Christ sitteth on the right hand of God. Set your affection on things above, not on things on the earth. For ye are dead, and your life is hid with Christ in God" (Colossians 3:1-3).

"For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them" (Ephesians 2:10).

Righteousness
"Blessed are they which do hunger and thirst after righteousness: for they shall be filled" (Mathew 5:6).

"Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven" (Mathew 5:16).

"And they were both righteous before God, walking in all the commandments and ordinances of the Lord blameless" (Luke 1:6).

"For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death" (Romans 8:2).

"That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit. For they that are after the flesh do mind the things of the flesh; but they that are after the Spirit the things of the Spirit. For to be carnally minded is death; but to be spiritually minded is life and peace. Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be. So then they that are in the flesh cannot please God" (Romans 8:4-8).

"Lord, who shall abide in thy tabernacle? who shall dwell in thy holy hill?He that walketh uprightly, and worketh righteousness, and speaketh the truth in his heart" (Psalm 15:1-2).

"Blessed are the undefiled in the way, who walk in the law of the LORD.Blessed are they that keep his testimonies, and that seek him with the whole heart. They also do no iniquity: they walk in his ways. Thou hast commanded us to keep thy precepts diligently. O that my ways were directed to keep thy statutes! Then shall I not be ashamed, when I have respect unto all thy commandments" (Psalm 119:1-6).

"I have inclined mine heart to perform thy statutes alway, even unto the end" (Psalm 119:112).

"For thou art an holy people unto the LORD thy God: the LORD thy God hath chosen thee to be a special people unto himself, above all people that are upon the face of the earth" (Deuteronomy 7:6).

Be Holy/Godly/Obedient-Zealous Of Good Works
"Wherefore gird up the loins of your mind, be sober, and hope to the end for the grace that is to be brought unto you at the revelation of Jesus Christ; As obedient children, not fashioning yourselves according to the former lusts in your ignorance:But as he which hath called you is holy, so be ye holy in all manner of conversation; Because it is written, Be ye holy; for I am holy" (1 Peter 1:13-16).

"Dearly beloved, I beseech you as strangers and pilgrims, abstain from fleshly lusts, which war against the soul; Having your conversation honest among the Gentiles: that, whereas they speak against you as evildoers, they may by your good works, which they shall behold, glorify God in the day of visitation" (1 Peter 2:11-12).

"Not purloining, but shewing all good fidelity; that they may adorn the doctrine of God our Saviour in all things. For the grace of God that bringeth salvation hath appeared to all men,teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly, in this present world; Looking for that blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ; Who gave himself for us, that he might redeem us from all iniquity, and purify unto himself a peculiar people, zealous of good works" (Titus 2:10-14).

The Holy Spirit Teaches Us All Things That Are Holy And True
"But ye have an unction from the Holy One, and ye know all things. I have not written unto you because ye know not the truth, but because ye know it, and that no lie is of the truth" (1 John 2:20-21).

"These things have I written unto you concerning them that seduce you. But the anointing which ye have received of him abideth in you, and ye need not that any man teach you: but as the same anointing teacheth you of all things, and is truth, and is no lie, and even as it hath taught you, ye shall abide in him. And now, little children, abide in him; that, when he shall appear, we may have confidence, and not be ashamed before him at his coming" (1 John 2:26-28).

Every One That Does Evil Hates The Light
"For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved" (John 3:20).

Lovers Of Pleasures More Than Lovers Of God
"This know also, that in the last days perilous times shall come. For men shall be lovers of their own selves, covetous, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy, without natural affection, trucebreakers, false accusers, incontinent, fierce, despisers of those that are good, traitors, heady, highminded, lovers of pleasures more than lovers of God; Having a form of godliness, but denying the power thereof: from such turn away. For of this sort are they which creep into houses, and lead captive silly women laden with sins, led away with divers lusts, ever learning, and never able to come to the knowledge of the truth" (2 Timothy 3:1-7).

Covetousness Unrighteous People Who Have Turned Away From God
"But these, as natural brute beasts, made to be taken and destroyed, speak evil of the things that they understand not; and shall utterly perish in their own corruption; And shall receive the reward of unrighteousness, as they that count it pleasure to riot in the day time. Spots they are and blemishes, sporting themselves with their own deceivings while they feast with you; Having eyes full of adultery, and that cannot cease from sin; beguiling unstable souls: an heart they have exercised with covetous practices; cursed children: Which have forsaken the right way, and are gone astray, following the way of Balaam the son of Bosor, who loved the wages of unrighteousness; But was rebuked for his iniquity: the dumb ass speaking with man's voice forbad the madness of the prophet. These are wells without water, clouds that are carried with a tempest; to whom the mist of darkness is reserved for ever. For when they speak great swelling words of vanity, they allure through the lusts of the flesh, through much wantonness, those that were clean escaped from them who live in error. While they promise them liberty, they themselves are the servants of corruption: for of whom a man is overcome, of the same is he brought in bondage. For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning. For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them" (2 Peter 2:12-21).

Put On The New Man With Righteousness And Holiness-Turn Away FromUnholiness- Don't Give Place To The Devil
"This I say therefore, and testify in the Lord, that ye henceforth walk not as other Gentiles walk, in the vanity of their mind, having the understanding darkened, being alienated from the life of God through the ignorance that is in them, because of the blindness of their heart: Who being past feeling have given themselves over unto lasciviousness, to work all uncleanness with greediness. But ye have not so learned Christ; If so be that ye have heard him, and have been taught by him, as the truth is inJesus: That ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts; And be renewed in the spirit of your mind; And that ye put on the new man, which after God is created in righteousness and true holiness. Wherefore putting away lying, speak every man truth with his neighbour: for we are members one of another. Be ye angry, and sin not: let not the sun go down upon your wrath: Neither give place to the devil.Let him that stole steal no more: but rather let him labour, working with his hands the thing which is good, that he may have to give to him that needeth. 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" (Ephesians 4:17-29).

"I beseech you therefore, brethren, by the mercies of God, that ye present your bodies as a living sacrifice, holy, acceptable unto God, which is your reasonable service. And be ye transformed by the renewing of your mind, that ye may prove what is the good and acceptable and prefect will of God (Romans 12: 1-2).
