Sex is great, or so I'm told. But the irony of sex is that it was specifically designed for marriage. If you have sex before or outside of marriage, it backfires. It becomes sin.
Drugs are similar. God deserves thanks for creating the plants that drugs come from because so much of our medication depends on them. Without drugs, diseases would be so much worse and death rates would be sky high. But if you take drugs the wrong way, it backfires. As good as a high may feel, where does it get you? Strung out on the floor and deep into sin.
Alcohol will do nothing for you except leave you puking into a toilet. And cigarettes won't help you unless you want to take fifteen years off your life. And fighting will only give you a beaten body and swollen pride. And stealing, cheating, and lying will only make you jumpy all the time and take away your peace of mind.
Nothing in this world brings true satisfaction. There are things that can be good, such as video games, friends, cool cars, winning the championship game, possessing a large paycheck, etc. But these things are so not worth living for. The only true thing in life worth living for is Jesus Christ. Only He brings true satisfaction. You've probably heard it said that Jesus wants to be the #1 priority in your life. He doesn't want to be #1. He wants to be your life. He wants to your your all, your everything, your Lord and Savior.
Christ came to give life. He didn't come to make it make our lives boring and miserable by keeping us from doing the "fun" stuff. He came to show us a better way to live. The things of this world are not of God. So don't live for things that are of the world, because 1 John 2 says, "If anyone loves the world, the love of the Father is not in him. For everything in the world—the cravings of sinful man, the lust of his eyes and the boasting of what he has and does—comes not from the Father but from the world. The world and its desires pass away, but the man who does the will of God lives forever."
Don't live for desires that pass away, that bring death, that separate us from God. Don't live for the things of this world, because everything here will eventually be destroyed. Live for God. Live for love. Life for life.
