What does the Bible say about imitation in the Christian life?

In 3 John 11-12, the Apostle John instructs us not to imitate what is evil but to pursue goodness. This contrasts two figures: Diótrefes, who represents a negative example, and Demetrio, who exemplifies a life aligned with God's truth. Imitation is an intrinsic part of human nature; we learn and grow by following examples. As Christians, the responsibility lies in ensuring that who we choose to imitate reflects the character of God, whose goodness should be the standard for our conduct.
