Well, that is an EXCELLENT example, my friend. Computers, networks, the Internet........how would early churches have been set up differently, how would they have proliferated, how much more efficiently would the Word have been spread given such things?
Now, what's OUR excuse? :) We have all of these things. I'm being somewhat facetious here; I do believe the Christian church is taking full advantage of such technologies to spread the Word, the story of Salvation through Jesus Christ. Add to that.......TV, radio....VERY powerful. I find it a wonderful thing.
Something I hadn't brought up earlier but is near and dear to my heart: music. I'm the lead guitarist in a praise and worship team in a reasonably large evangelical church. I will tell you......there is NO way 1st century instruments can carry the power of God's Word to the masses the way a stage full of musicians can today. NO way. I take full advantage of the music technology available to me to convey the pure POWER of Jesus' love; the message that He is the way, the truth, and the light....that it is through Him and Him only that we achieve salvation. I do it LOUDLY and very proudly.
It happens to be my ministry. I'll never be an evangelist or missionary.....but I can play praise and worship music and affect many, many people; and I have, through His graces. It's how I give back to the one who died for me a little over 2000 years ago. He took a bullet for me........this is what I do for Him in return in my own small way.
Music can be extremely powerful.
One church I attended several years ago had a praise song that had some heavy drum beats that made me imagine the music that was probably played as the OT armies marched into battle against those inhabiting the Promised Land.
That also explains why I like high school/college drum lines so much.
There is nothing wrong with music getting our hearts right and our minds fertile for the Word.
