¹⁸ Little children (believers, dear ones), let us not love [merely in theory] with word or with tongue [giving lip service to compassion], but in action and in truth [in practice and in sincerity, because practical acts of love are more than words]. ¹⁹ By this we will know [without any doubt] that we are of the truth, and will assure our heart and quiet our conscience before Him ²⁰ whenever our heart convicts us [in guilt]; for God is greater than our heart and He knows all things [nothing is hidden from Him because we are in His hands].
