The short answer: Of course!
Long answer: First let us delve into proclaiming the Gospel. God calls every one of us to proclaim the Good News He brings.
"And he said, “Yes, it was written long ago that the Messiah would suffer and die and rise from the dead on the third day. It was also written that this message would be proclaimed in the authority of his name to all the nations, beginning in Jerusalem: ‘There is forgiveness of sins for all who repent.’ You are witnesses of all these things." Luke 24:46-48 NLT
So we have the task. What about the method? In the words of Paul:
"Pray for us, too, that God will give us many opportunities to speak about his mysterious plan concerning Christ. That is why I am here in chains. Pray that I will proclaim this message as clearly as I should. Live wisely among those who are not believers, and make the most of every opportunity."
Colossians 4:3-5 NLT
Paul is a very wise man because he knew very well that people of all different cultures are going to be reading his words. The method is that God provides the opportunities wherever we are at. Paul is calling us to make the most of every opportunity to proclaim the Good News. Paul himself was proclaiming from a prison cell! If he can do that, then we can proclaim anywhere God provides.
God has provided us with amazing resources in this the 21st century. If we should not use them then we would be neglecting the words of Paul. We can send a message across the world in a millisecond, we can fly anywhere we want to, reach the entire globe through the internet and God has given us these great gifts, it would be a shame not to use them!
In conclusion, there is truly something significant about the trends of the 21st century that Christians everywhere can make the most of sharing this magnificent news--that those who believe that Jesus Christ defeated death and rose again to erase their sins and grant eternal life--in every possible circumstance.
