What it means to be a real Christian

Therefore, to be a Christian is not merely to bear the name of Christ and say, "I belong to a Christian government." To be a real Christian is to be a servant in His Cause and Kingdom, to go forth under His banner of peace and love toward all mankind, to be self-sacrificing and obedient, to become quickened by the breaths of the Holy Spirit, to be mirrors reflecting the radiance of the divinity of Christ, to be fruitful trees in the garden of His planting, to refresh the world by the water of life of His teachings -- in all things to be like Him and filled with the spirit of His love. (Abdu'l-Baha, The Promulgation of Universal Peace, p. 6)
