Like other inventions, the Internet has brought much good to the human race—but it also has brought much evil. The explosion in Internet pornography is vicious and corrupting, and is one reason why I believe parents should monitor very closely what their children are accessing on their computers.
Others may not know what you are doing in the privacy of your room—but God does, and some day you will stand before Him to give an account of the way you allowed your mind to be filled with this evil. The Bible warns, "Nothing in all creation is hidden from God's sight. Everything is uncovered and laid bare before the eyes of him to whom we must give account" (Hebrews 4:13). These are sobering words, and you should take them seriously.
But listen: God loves you, and He doesn't want you to be enslaved by your lusts. Instead, He wants to free you—and He will, if you will let Him. Jesus said, "If the Son sets you free, you will be free indeed" (John 8:36). I urge you to claim this promise as your own.
Begin by confessing your sins to Christ, and asking Him to forgive you and cleanse you and fill you with His Holy Spirit. Then take practical steps to avoid temptation—by setting up anti-porn filters on your computer, for example, and moving it to a public place.
