The question is often asked “If God elects, what is the purpose of evangelism?” Though it would seem that this is a relatively strange question for any Christian to ask, the fact that it’s a common objection to the doctrine of election and predestination means we should probably talk about it.
Now, smarter men than I have written great books on the importance of evangelism. One of my personal favorites is Evangelism and the Sovereignty of God by J.I. Packer. He lays out the idea of an antinomy (or type of paradox) for the reason we must hold fast to the Great Commission even when God chooses who believes. I won’t spend too much time regurgitating the book, it’s worth the read in itself. Instead I will give you the Tl:dr (internet speak for “too long, didn’t read) version of “why evangelize”.
Are you ready?
Because God says so.
In all seriousness though this is the truth. The Apostle Paul tells us that he isn’t ashamed of the Gospel of Jesus Christ, for it is the power of God unto salvation. (Romans 1:16) It is the vehicle in which God has chosen to quicken the heart of the elect. We know this because Paul says again in Romans that faith comes from hearing and that hearing comes from the word of Christ (10:17). In God’s amazing plan for humanity, He has chosen the Gospel of Jesus to be the word that activates the faith in the believer. The same faith to believe unto salvation.
“How then will they call on him in whom they have not believed? And how are they to believe in him of whom they have never heard? And how are they to hear without someone preaching?And how are they to preach unless they are sent? As it is written, “How beautiful are the feet of those who preach the good news!” Romans 10:14-15
What I love about the book of Romans is that it was written to establish a basis of theology for all believers during the time of it’s writing. It was written to the church in Rome, the largest of the churches, to be disseminated to the rest of the bodies of believers. It answers so many questions that even we as believers have today in the 21st Century.
We preach the Gospel because God has ordained it to be the way others believe in Jesus Christ. I’ll leave you with one of my favorite Charles Spurgeon quotes:
“If God had put a yellow streak up and down the backs of the elect, I’d go up and down the streets lifting up shirt tails to find out who had the yellow streak up and down his back. Then I’d give that person the gospel. But God didn’t do that. He told me to preach the gospel to every creature and that whosoever will may come.” That is our marching order, and as far as I am concerned, until God gives me the roll call of the elect, I am going to preach the “whosoever will” gospel. That is the gospel we are to preach today.” (this quote is not directly tied to Spurgeon in one of his writings, instead recorded as an account from a dialogue he had)
