James 3: 1-18

19 And he took bread, gave thanks and broke it, and gave it to them, saying, “This is my body given for you; do this in remembrance of me.” - Luke 22:19

20 In the same way, after the supper he took the cup, saying, “This cup is the new covenant in my blood, which is poured out for you.” - Luke 22:20

What you say is important

“Both glory and disgrace come from speaking” Sirach in the Book of Virtuous wisdom: “Both glory and disgrace come from speaking”

“Faith without works is dead” Your words are one of your works

Those who consider themselves religious and yet do not keep a tight rein on their tongues deceive themselves, and their religion is worthless - James 1:26

Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen. - Ephesians 4:29

33 “Make a tree good and its fruit will be good, or make a tree bad and its fruit will be bad, for a tree is recognized by its fruit. 34 You brood of vipers, how can you who are evil say anything good? For the mouth speaks what the heart is full of.

35 A good man brings good things out of the good stored up in him, and an evil man brings evil things out of the evil stored up in him. 36 But I tell you that everyone will have to give account on the day of judgment for every empty word they have spoken. 37 For by your words you will be acquitted, and by your words you will be condemned.”

God alone can tame our tongue
