(1 Cor. 6:12)-"POWERFUL PRINCIPLES FOR PROPER PRACTICE"(Is it RIGHT or Is it WRONG?)
Intro: While I lived in Los Angeles I played "Pop Warner" Football, named after a famous football coach of days gone by.  It was the year 1908, Syracuse verses Carlisle. As the teams made ready for the game, the Carlisle coach, Pop Warner, decided to bend the rules to give his team the upper hand. He was a good coach, but he wasn’t above bending the rules when it was to his advantage. Before the game, he had them sew what looked like footballs into the front of their jerseys, so that the other team wouldn’t know who had the ball! Now, there was no written rule against it, but it violated all the principles of fair play! There are many Christians who wish that the Bible contained specific rules governing every possible situation in life. Then, they think, they would know what they should do in every situation. They would know what they could do and what they could not do. A book like that would be too big to read, so men would still be in the dark. God has, however, given us a book that contains all the principles that we need to be able to live for Him in this world.
In this verse, and on through chapter 10, Paul lays out several very important principles for the Corinthian believers. You see, he is writing to some very immature Christians, some babes in Christ that needed to grow up!  He tells them so in 3:1. He reminds them, that like little children, they think there is a rule for everything...like little kids at play! Before long, someone is going to yell, “That’s not fair!” Kids need, and by the way, love rules! As children grow up and become old enough to leave home alone, we lay out all kinds of rules for them to go by. But, when they are grown, you don’t want to keep having to tell them every thing to "do and not do!"  By then, they should have established in their lives some principles by which they can live their lives. By doing so, they will know how to respond in any situation!
Today, I want to share with you some Powerful Principles For Proper Practice that will give us God’s standard by which we can live our lives. These principles, if practiced, will teach you how to live your life, and respond to any questionable situation or activity. Hundreds of times each year, someone asks me if a particular action is RIGHT or WRONG? (Holy Spirit's job!)  As we grow in Christ, we need to be liberated from the legalism of rules and learn to apply these principles to life that we might know how to live, without someone having to tell us every move to make. The ability to make decisions wisely is a mark of maturity! These aren’t rules, these are lessons that every Christian would do well to learn and use.
I. 6:12- THE PRINCIPLE OF EXPEDIENCY-This is a compound principle. There are 2 questions raised here that can help you decide whether something is right or wrong.  
(1)-Is It Lawful? Is there any word from God concerning the matter?  When God speaks on an issue, it is settled!- 2 Tim. 3:16! -(There are some very clear moral absolutes!) 
(2)- Is It Expedient?  Expedient mean, “To bring toward a destination, to end th right way!”   Every decision or activity either moves us toward or away from Jesus Christ!  So you must ask yourself, “Does this thing bring me closer to Jesus?” If it doesn’t, then it is wrong! (As for goals, every believer should have them -Paul - Phil. 3:13-15!) (Does this thing get me closer to where I need to be, or not?”)
Some have the attitude, "I can do anything I please, and it will not make me unsaved"! (Maybe...maybe you aren't saved to begin with if you're thinking that way!  Yes, I can literally do everything, but everything I do will help me grow as a Christian, and if it doesn’t bring me closer to my destination, it is wrong!  It doesn’t matter what it is! (God’s plan for you and me is to be More like Jesus! - Eph. 4:13!)
II. 6:12- THE PRINCIPLE OF ENSLAVEMENT
To be “brought under power” means to be enslaved!  We were all slaves at one time, slaves to sin - Eph. 2:1-3; Rom. 6:16), but we have been delivered by the Lord Jesus!  Anything outside Jesus that controls my life is a sin! (There are only 2 forces in operation in the world! - Matt. 12:30) (The lost man thinks he is in control, but he isn’t! He is free to choose his actions, but not the consequences of those actions, he is a slave to the will of the devil!)   John 8:36-"Whoever the Son sets free is FREE INDEED!"   We need to search our lives and be sure that no habit, attitude, activity, pursuit, etc. has us enslaved. If you are struggling with some “besetting sin”, Jesus can set you free today!
III. 8:8-13 -THE PRINCIPLE OF EXAMPLE
Corinth, where Paul lived, was a pagan society. Many who lived there practiced idol worship. They would sacrifice a sheep or a goat to their god and then they would sell the meat to the butcher at the meat market. He, in turn, would make the meat available to the public at a discount price. It was perfectly good meat and the price was right, so some Christians would by this meat and eat it. Other Christians, however, felt that God’s people shouldn’t eat this meat because it had been offered to devils. These opposing camps began to argue bitterly about this issue, and they turned to Paul for help and he, through the inspiration of the Lord, gave them this Principle Of Example.
Paul did not give them an ironclad rule, but rather, he gave them a principle. He said that meat would not make you better neither would it make you worse. However, his advise was this, don’t do anything that would make you a stumblingblock to another believer. The issue is not, “Will it hurt me?” The question is, “Could it hurt my brother?” (Others are supposed to come first! - Phil. 4:2)  Each side thought they were right and possessed greater insight into the issue, but Paul reminds them that brotherly love must be the main objective - 8:1.
You and I possess great liberty in the Lord and could lawfully do many things, but we must always be mindful of the example we are setting for others. We must never do anything that will cause another brother to stumble - Matt. 18:6! (Drinking or smoking for example!-Signs that say, "This is a no-smoking facility") The Christian must always consider his brethren before himself!
IV. 10:23 -THE PRINCIPLE OF EDIFICATION
“To edify” - “To build up”  Everything you do, say, hear, etc. is either building you up, or tearing you down.  Every conversation, every relationship, ever activity must be judged by the same principle, “Does this thing make me stronger in the Lord, or does it weaken my walk with Jesus?”  All of life should be lived in such a way that it does nothing but build us up in the Lord Jesus. Do the things you are doing make you stronger for Him? If not, they need to go!
V. 10:31 -THE PRINCIPLE OF EXALTATION
Everything we do in life either honors or dishonors God! (Every conversation, habit, relationship, business deal, vacation, book read, film watched, music listened to, etc.)   WWJD - “What Would Jesus Do?” Learn to ask yourself this question! Another good one to ask is this, “What would I do if Jesus were with me?” -(Jesus Christ, the same yesterday, and today, and forever.!") Heb. 13:5   (Remember, as a Christian, everything you do reflects back on God. It can be positive, or negative,  Phil. 1:27. Does your life exalt God in the eyes of the world?)
VI. 10:32-33- THE PRINCIPLE OF EVANGELISM-Paul’s desire was this; He did'nt want to turn anyone off of God and the Bible by his lifestyle. Therefore, he strove to inoffensive and an open book in his walk with the Lord.  PEOPLE READ YOU LIKE A BOOK!  People are watching you! Does your life move men toward God or away from Him?  Lifestyle does matter! “What you do speaks so loud that people can't hear a word you are saying!”   We should strive to reach everyone we come into contact with for Jesus, but it won't work as long as our talk and walk do not agree!  Conc: If you and I will take these six principles and live our lives by them, we will be a blessing to the Lord’s work in this world.  And at the end of the way, we will meet Jesus face to face and He will say, “Well done god and faithful servant!” Don’t know about you, but that’s what I want to hear! Doing these things in regard to the issues of life will make that hope a reality!
