Realism is a form of art that's solid aim is to paint or build art in as much realistic detail as possible. Why then, when it comes to evangelism, does it seem to be so foreign to us? What if it is way easier then we make it out to be?
While you might feel you play no role in the grand scheme of things, take a lesson from the hand of an artist who practices impressionism. You might learn to change your perspective.
Evangelism is possible! It is not a lost art, but it exists in the very opportunities that your life gives you. Embrace opportunities and share the good news of Jesus with others!
