How do we know that judging is necessary for Christians?

The necessity of judging is inherent in the Christian life as believers are called to discern right from wrong in various contexts, including doctrine and behavior within the church. Luke's account conveys that the disciples understood that judging properly was part of their responsibility. This discernment is vital for upholding truth and ensuring that believers engage faithfully with the teachings of Scripture. We are to judge with fairness, using the measure of grace and love we have received from God, thereby reflecting His character in our actions.
