Some people erroneously believe that since certain things are not prohibited in the Bible, then they must be O.K. Sorry to disappoint them, but that it's not so. Today there are many things, that were not available in biblical times, nevertheless biblical principles still apply to them.
Tobacco and drugs were unknown in olden times, but the Bible clearly says, " The merciful man doeth good to his own soul: But he that is cruel troubleth his own flesh". (Proverbs 11:17) A modern rendering is "The merciful man does himself good, but the cruel man does himself harm". (Proverbs 11:17, NAS). There are proper uses for tobacco but smoking it is not one of them. There are proper uses for drugs, but using them without medical authorization is not one of them. The principle is very simple if this modern item or practice will hurt your person, then do not do it.
Man has a great capacity for invention and creativity, and there is absolutely nothing wrong with the inventions, the problem is usually how the inventions are used. Man always manages to turn any new invention for evil purposes. The telephone is a great communication tool, but the phone line carries whatever is put into it from a cursing to a blessing; from a prayer to a death threat. Electricity our friend has been used in instruments of torture, and death. The Amish decided to do without electricity, but I hardly think that the proper Christian response is to do without certain things because they have been put to an evil purpose by some people.
The Internet which was created for scientific endeavors is now the playground of pedophiles, terrorists, and other evil men who roam in there. Of course no one is advocating getting rid of the Internet any more than anyone is asking people to give up their cameras; just because cameras are used for pornography. The problem is not the modern tools but that quite often modern tools are twisted to evil means.
Movies were also unknown, but the Bible says "I will set no wicked thing before mine eyes". (Psalm 101:3). So before a person goes to the Movies or turns on the TV, that person needs to ask whether the movie or show will be something positive or negative. It goes without saying that no Christian should watch a triple x rated movie and I would encourage Christians not to watch horror movies, for they are definitely not positive. Yes I know the blood is ketchup, and the guts are probably made of plastic or are from pigs, but their message is not decent.
There are other things like; rock & roll, Rap, Dancing, Fantasy games, Video games, and many other modern things. But they are all basically covered by, I Thessalonians 5:22 "Abstain from all appearance of evil". Yes I am aware that some have attempted to sanitize those things and use them for Christian purposes, but I am a little skeptical of using the world’s inventions for evangelism. I cringe when I hear of Christian rock, Christian rap or any other Christian modern thing. Yes I know that David danced before the Lord and the children of Israel praised the Lord with dancing, but I am quite sure they were not twerking.
Does this mean that all modern inventions are evil? That we cannot watch movies or play video games? No, it means that we are to judged all things before we engage in any of them. Before you watch a movie, have you checked the ratings it has? Before you play a Video game have you seen the reviews for this game? Before you engage in anything of this world, get informed. However, even a bad thing can be turned for good. Some Christians have begun to make good and wholesome videos, and others have begun to make excellent ministerial web pages.
God has made man upright; but they have sought out many inventions.(Ecclesiastes 7:29) Yes, they are inventors of evil things. (Romans 1:30)
