It has always been my ambition to preach the gospel where Christ was not known, so that I would not be building on someone else’s foundation. 21 Rather, as it is written:
“Those who were not told about him will see,
and those who have not heard will understand.”
22 This is why I have often been hindered from coming to you. 23 But now that there is no more place for me to work in these regions, and since I have been longing for many years to visit you, 24 I plan to do so when I go to Spain. I hope to see you while passing through and to have you assist me on my journey there, after I have enjoyed your company for a while
When I went to a Christian Missionary Alliance Church, I learned that their emphasis for missions was based on this verse in Matt. 24:14, "And this gospel of the kingdom will be preached in the whole world as a testimony to all nations, and then the end will come." They believed that the one thing holding back the second coming of Christ was unreached people groups. Now whether that's a correct interpretation of the passage or not doesn't really concern me. Any church with an emphasis of taking the (true) gospel out to the world is fine by me.
We learn several things about Paul from these few verses. First, his primary gifting was evangelism not discipleship. Sure, he stayed in some cities for months at a time and met with believers at a school but those seemed more the exceptions. His personal discipleship consisted of taking guys along with him on his trips like Silas, Timothy, and Luke. Paul was basically an itinerant speaker going to areas that hadn't heard the gospel, preaching it for several days and then moving on usually for the fear of his life. That was God's plan for him at this point. Throughout my Christian life, I have heard travelling evangelists at revival weeks at every different denomination I'm in. Usually, they come for a love offering and are meant to save the lost and rekindle the backslidden. I'm sure they say that Paul is their inspiration for ministry.
I often wonder if evangelists, like Paul with John Mark, have limited patience with people. I can see this with myself; I don't like to go on mission trips where I've been before. Hundreds will have been saved, and I go back a year later and none of those converts are in the church. How can you hear something as wonderful as the gospel and not experience radical life change. Or I meet with kids in the youth group to disciple and I give them verses to read with a journal to fill out - main thought, what God is saying to me, Action I'm going to take. How difficult is that? They don't do it or say they will meet me and don't show. Personally, I don't think Paul would have put up with that. I don't want to question Paul's motivation as he justifies it with an Old Testament prophecy or says, "God hasn't allowed me to come to you", but I think Paul's personality was certainly suited for a travelling evangelist. His zeal was so great that there were no places left to preach - how could he put up with someone who is unexcited about Jesus?
Second, he wasn't embarrassed to ask for support. I tend to think any ministry that is asking for money is suspect due to all the scams and greedy people out there, but legitimate ministries should not be ashamed to ask for money. In fact, although a church in Lystra might not be evangelizing the nations, by helping Paul financially, they in effect are. I've been to multiple missions' conferences growing up, also, where a missionary on a brief furlough, comes to a church that supports them and tells of the fruit of their labor which wouldn't have been possible without your financial support. We feel somewhat responsible for the Bible being translated into an unreached people group's language in the Ivory Coast through Verne and Denny Johnson. They did all the work, but we had a small part and so glad we have supported them.
