By your words you will be declared righteous, or you will be condemned (Matthew 12:35–37)

“The good man out of his good treasure sends out good things, whereas the wicked man out of his wicked treasure sends out wicked things. 36 I tell you that every unprofitable saying that men speak, they will render an account concerning it on Judgment Day; 37 for by your words you will be declared righteous, and by your words you will be condemned” (Matthew 12:35–37).
Jesus Christ showed that the words reveal the state of the symbolic heart of the human: “A good man brings forth good out of the good treasure of his heart, but a wicked man brings forth what is wicked out of his wicked treasure; for out of the heart’s abundance his mouth speaks” (Luke 6:45).
Speaking of the eleven faithful apostles, Jesus Christ said that they were inner clean: “And you men are clean, but not all.” He knew, indeed, the man betraying him. This is why he said: “Not all of you are clean”” (John 13:10,11). Why were the eleven apostles clean? Quite simply, the intentions of their hearts were pure. Why was Judas Iscariot not inner pure? Because of the evil intentions to betray his master, Jesus Christ. A little later in the narrative of John 13, it is written that Satan “entered” into Judas (John 13:27). This does not necessarily mean that Satan was made master of the free will of Judas Iscariot, but rather that he allowed himself to be carried away by his diabolical reasonings to betray his master.Thus, as Jesus Christ again taught, it is the evil reasonings of the heart that make spiritually unclean a person (Matthew 15:17–19).
When the disciples of Christ, following the example of the eleven faithful apostles, have a clean heart, with good intentions then, to use an image of the apostle Paul, they bring Christ into their hearts and dwelling in them: “On account of this I bend my knees to the Father, to whom every family in heaven and on earth owes its name, to the end that he may grant you according to the riches of his glory to be made mighty in the man you are inside with power through his spirit, to have the Christ dwell through your faith in you hearts with love; that you may be rooted and established on the foundation, in order that you may be thoroughly able to grasp mentally with all the holy ones what is the breadth and length and height and depth, and to know the love of the Christ which surpasses knowledge, that you may be filled with all the fullness that God gives” (Ephesians 3:14–19).
In the teaching on the good and bad use of the tongue, the disciple and brother of Jesus Christ, James, in chapter 3 of his letter, wrote this: “So, too, the tongue is a little member and yet makes great brags. Look! How little a fire it takes to set so great a woodland on fire! Well, the tongue is a fire. The tongue is constituted a world of unrighteousness among our members, for it spots up all the body and sets the wheel of natural life aflame and it is set aflame by Gehenna” (James 3:5,6). According to this text, the bad use of the tongue has the terrifying power to condemn to Gehenna fire, that is to say, to a death without possibility of resurrection, because, he wrote, “it spots up all the body and sets the wheel of natural life aflame and it is set aflame by Gehenna”. So, to avoid such a dramatic end, we must cultivate wisdom from above: “But the wisdom from above is first of all chaste, then peaceable, reasonable, ready to obey, full of mercy and good fruits, not making partial distinctions, not hypocritical. Moreover, the fruit of righteousness has its seed sown under peaceful conditions for those who are making peace” (James 3:17,18).

“But as for me, I will keep on the lookout for Jehovah. I will show a waiting attitude for the God of my salvation. My God will hear me” (Micah 7:7).
