I'm not aware of the place in the NT where it says that Evangelism is the highest calling of a Christian. I do know that Jesus regularly said "Follow me." I suppose that I should then say that following Jesus is the highest calling of a Christian. Part of following Jesus includes evangelism. Which is not the same thing as saying that Evangelism is the highest calling.Paul wrote:The leader, Florens van der Spek already made national television proclaiming Jesus as Lord, impressively handling the mockery and pointing to Jesus as God, and telling everyone we need Him for every aspect of our lives etc. and today in the newspaper he commented like this "Evangelism is the highest calling of a Christian. This also goes for politics.
A personal reflection: Recently I stopped attending an evangelical Protestant campus ministry because I am not interested in living how the young men there live. In a later conversation with one of the men, he suggested that I consider how the organization needs people to spread the Gospel, regardless of how they are living. I think that way of thinking and living is the outcome of making Evangelism into our highest calling.
