The only time when Jesus said, “I gave you an example,” is in John 13 where He emphasized the need to be a servant, and the mark of our discipleship comes from the way we treat one another.
Paul encouraged Christians to follow his example (1 Co. 11:1). He told Timothy to be an example of the believers in speech, conduct, love, faith and purity (1 Tim. 4:12). The world needs Christians to be an example in marriage and parenting, in ethical business conduct, and being a good neighbor.
We can provide no greater gift in leading others to Christ than setting a good example.
