"Be ready to speak up and tell anyone who asks why you're living the way you are, and always with the utmost courtesy."
That means we live in close enough contact with those seeking truth, and in such a way that they see us living a life worth asking questions of - not us knocking on their doors and asking questions of virtual strangers.
The Fruit of the Spirit
How does the Spirit of God manifest itself through us? Often we think that to witness means to speak up in defense of God. This idea can make us very self-conscious. We wonder where and how we can make God the topic of our conversations and how to convince our families, friends, neighbors, and colleagues of God's presence in their lives. But this explicit missionary endeavour often comes from an insecure heart and, therefore, easily creates divisions.
The way God's Spirit manifests itself most convincingly is through its fruits: "love, joy, peace, patience, kindness, goodness, trustfulness, gentleness and self-control" (Galatians 5:22). These fruits speak for themselves. It is therefore always better to raise the question "How can I grow in the Spirit?" than the question "How can I make others believe in the Spirit?"Henri Nouwen
