Christian and Faithful, fellow travelers from the City of Destruction to the Celestial City, meet with Talkative -- a wanderer who loves to talk of spiritual things but has no work of Christ in his life.
This Talkative is not aware of; he thinks that hearing and saying will make a good Christian, and thus he deceiveth his own soul. Hearing is but the sowing of the seed; talking is not sufficient to prove that fruit is indeed in the heart and life; and let us assure ourselves, that at the day of doom men shall be judged according to their fruits. [Matt.13, 25] It will not be said then, Did you believe? but, Were you doers, or talkers only? and accordingly, shall they be judged. The end of the world is compared to our harvest; and you know men at harvest regard nothing but fruit. Not that anything can be accepted that is not faith, but I speak this to show you how insignificant the profession of Talkative will be at that day.
~The Pilgrim's Progress from This World to That Which Is to Come
by John Bunyan
Jesus said... “Beware of false prophets, who come to you in sheep's clothing but inwardly are ravenous wolves. You will recognize them by their fruits. Are grapes gathered from thornbushes, or figs from thistles? So, every healthy tree bears good fruit, but the diseased tree bears bad fruit. A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire. Thus you will recognize them by their fruits."
From the Passion Week... On the following day, when they came from Bethany, he was hungry. And seeing in the distance a fig tree in leaf, he went to see if he could find anything on it. When he came to it, he found nothing but leaves, for it was not the season for figs. And he said to it, “May no one ever eat fruit from you again.” And his disciples heard it. [...] As they passed by in the morning, they saw the fig tree withered away to its roots. And Peter remembered and said to him, “Rabbi, look! The fig tree that you cursed has withered.” And Jesus answered them, “Have faith in God. Truly, I say to you, whoever says to this mountain, ‘Be taken up and thrown into the sea,’ and does not doubt in his heart, but believes that what he says will come to pass, it will be done for him. Therefore I tell you, whatever you ask in prayer, believe that you have received it, and it will be yours. And whenever you stand praying, forgive, if you have anything against anyone, so that your Father also who is in heaven may forgive you your trespasses.”
~Mark 11:12-14, 20-25
