John Of Kronstadt. (№ 448494)

If we do not kindle the warmth of faith in our hearts, then faith can be completely extinguished in us due to negligence; Christianity, with all its sacraments, may, as it were, die completely for us. The enemy is only trying to extinguish faith in the heart and bring into oblivion all the truths of Christianity. That is why we see people who are Christians by name only, but by their deeds they are perfect pagans.
