Look into your bible and see how christians ought to live. See how the bible says those who are christians _must_ live, and then if you find your christian friends living in a _different_ way, instead of having cause for feeling that you may do so too, you have only cause to fear that they are deceiving themselves with the belief that they are christians, when they are not. Remember that the farther your christian friends depart from the standard of christian character laid down in the bible, the less reason have you to hope that they _are_ christians. And do not hesitate on this subject because you find _many_ professed christians, who are indifferent and lax in their practice and example. Remember that Christ has said, “_Many_ shall say unto me in that day, Lord, Lord,” thus claiming to be his disciples, to whom he will say, “I never knew you.” Do not let _professed_ christians tempt you to fall into the society of such unhappy _castaways_. 13. Do not be _periodical_ christians. There are some who profess religion, who never seem to feel any interest on the subject, except when every one else does. It is true, there are special seasons of revived religion in the hearts of all christians, but if it is only at such times that progress is made in divine life, and interest is manifested in the salvation of souls, there is great reason to fear that what is called religion is nothing but sympathy with the feelings of others. 14. Do not let the adversaries of the cross have occasion to reproach religion on your account. How holily should the children of God, the redeemed and the beloved of the Son of God, behave themselves. Therefore, “walk as children of the light, and of the day,” and “adorn the doctrine of God your Saviour;” and especially, abound in what are called the Christian virtues, and make you like the Lamb of God: be meek and lowly of heart, and full of pure, heavenly, and humble love to all; abound in deeds of love to others, and self-denial for others; and let there be in you a disposition to account others better than yourself. 15. Be sure that there exists a _marked difference_ between _your_ appearance and conduct, and that of those who are not christians. Remember that Christ has required this of you, and that even _the world_ expects it.
