Lk 9:23 — And He was saying to them all, “If anyone wishes to come after Me, he must deny himself, and take up his cross daily and follow Me. 24For whoever wishes to save his life will lose it, but whoever loses his life for My sake, he is the one who will save it. In conclusion, let every reader of this paper think seriously, whether his religion costs him anything at present. Very likely it costs you nothing. Very probably it neither costs you trouble, nor time, nor thought, nor care, nor pains, nor reading, nor praying, nor self-denial, nor conflict, nor working, nor labour of any kind. Now mark what I say. Such a religion as this will never save your soul. It will never give you peace while you live, nor hope while you die. It will not support you in the day of affliction, nor cheer you in the hour of death. A religion which costs nothing is worth nothing. Awake before it is too late. Awake and repent. Awake and be converted. Awake and believe. Awake and pray. Rest not till you can give a satisfactory answer to my question, "What does it cost?"
