Plzzz i'm taking the test right

in which quotation from the text does the author develop the idea that throughout life, people must remain vigilant in following their faith to be received in heaven?

“christian doubts whether he can make it across, for the memory of his past sins weighs on him once again, but hopeful reminds him that christ’s love will take away those sins.”

“the two friends…travel onward to vanity fair, a magnificent fair established by satan, where all sorts of tempting luxury items are sold. after refusing to give in to the temptation of worldly possessions, christian and faithful are imprisoned by the residents of vanity fair, and faithful is burned at the stake.”

“three angelic beings called the shining ones appear and give christian a scroll of the bible, which will be his ticket into the celestial city, but christian falls asleep and loses it. christian now realizes that he needs to stay wakeful in order to reach salvation.”

“as the pilgrims continue, they are tempted by a series of characters who try to convince them that religion and the pursuit of wealth can be combined.”
