Contextual ministry sounds like a complicated concept, but it's really pretty simple. It's about adopting the attitude of a missionary in every setting that we are in - so that, through our words, our actions, and most importantly our love, people ma come to know the love and the person of Jesus Christ.
It's simple, but it's not easy. Mahatma Gandhi said "I like your Christ, I do not like your Christians. Your Christians are so unlike your Christ." Being relevant in our culture does not mean changing our convictions, values or beliefs. However, it does mean being willing to change our methods and the way we relate to people.
