Throughout the scripture setting an example is stressed as an important element of discipleship.
In Matthew 11:29 we are told to "Take my yoke upon you." - Jesus told his followers to learn from his example of gentleness and humility.
As the body of Christ, believers must show Christ to the world by being examples. Nonbelievers should be able to see Christ in believers and be so drawn to what they see that they seek Christ and his salvation. What kind of example are you?
