What a wonderful opportunity God has given us to reach and teach disciples in small groups! The best way to do this is by example. Just as we follow the example of the New Testament church, we teach and are taught by the examples of those around us. How many times have you personally met someone and thought, "I want to be like them"? Or, just as significantly, "I don't want to be like them!" Our relationships with those in our small groups, whether they be newcomers to Christianity or newcomers to the concept of Christian community, will have an incredible impact on their lives.
Our examples will determine if that impact is positive or negative. Have you heard the saying, "You may be the only Bible some people ever read"? This is probably more true if they come away thinking "I can't believe they call themselves Christians!" On the other hand, if the community they encounter is one of love and sharing and acceptance, they will be drawn to a relationship with Christ and to His Body, and will be moved to follow our examples.
Jesus confirmed his role of teacher in John 13:13 , and in verse 15, he explains further, "I have set you an example that you should do as I have done for you." We are all familiar with Jesus' example: love, love, love! He reached out to the downcast of society and treated everyone special. We have all seen the love of God work miracles in our far from worthy lives; we need to be the extensions of His hand. In verses 34-35, Jesus confirmed that everyone will know we are His disciples if we "love one another" as He loved us.
One of my favorite axioms is this: "People don't care how much you know until they know how much you care."
