The new convert is tested to see if the words he professes are justified with corresponding fruit in his life. Christian's - John Bunyan

...Great sins do draw out great grace; and where guilt is most terrible and fierce, there the mercy of God in Christ, when showed to the soul, appears most high and mighty...

Fear, lest, by forgetting what you are by nature, you also forget the need that you have of continual pardon, support, and supplies from the Spirit of grace, and so grow proud of your own abilities, or of what you have received from God.

But now in this Valley of Humiliation poor Christian was hard put to it, for he had gone but a little way before he espied a foul Fiend coming over the field to meet him; his name is Apollyon. Then did Christian begin to be afraid, and to cast in his mind whether to go back, or to stand his ground. But he considered again, that he had no Armor for his back, and therefore thought that to turn the back to him might give him greater advantage with ease to pierce him with his Darts; therefore he resolved to venture, and stand his ground. For thought he, had I no more in mine eye than the saving of my life, 'twould be the best way to stand. So he went on, and Apollyon met him. Now the Monster was hideous to behold, he was cloathed with scales like a Fish (and they are his pride) he had Wings like a Dragon, feet like a Bear, and out of his belly came Fire and Smoke, and his mouth was as the mouth of a Lion. When he was come up to Christian, he beheld him with a disdainful countenance, and thus began to question with him.
