Probably the most prolific person in the Bible besides Jesus was a missionary. We can read about his ministry work in 13 books of the New Testament. The Apostle Paul was a traveling man and even before he met Jesus on the road to Damascus, he frequently was on the road persecuting early Christians. Outside of Paul's work, all Christians are commanded to GO! Why would God want us to travel so much?
...Because God said so
19 Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.”
47 For so the Lord has commanded us, saying, "' I have made you a light for the Gentiles, that you may bring salvation to the ends of the earth.'"
This popular website actually lists 12 verses that they believe support missions work.
Does this mean that all of us are called to be foreign missionaries sweating in the jungle? Of course not. I tell people all the time that it takes a team to do missions work. Here are just a few components:
Supporters (financial and prayer)
Short term mission teams
God has designed us to all have specific talents and gifts. Simply put...There are senders and goers. BUT....we should ALL be the hands and feet of Jesus while we are here on earth.
