29 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.
19 My dear brothers, take note of this: Everyone should be quick to listen, slow to speak and slow to become angry, 20 for man's anger does not bring about the righteous life that God desires.
21 "You have heard that it was said to the people long ago, 'Do not murder, and anyone who murders will be subject to judgment.' 22 But I tell you that anyone who is angry with his brother will be subject to judgment. Again, anyone who says to his brother, 'Raca, 'is answerable to the Sanhedrin. But anyone who says, 'You fool!' will be in danger of the fire of hell.
43 "You have heard that it was said, 'Love your neighbor and hate your enemy.' 44 But I tell you: Love your enemies and pray for those who persecute you, 45 that you may be sons of your Father in heaven. He causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous. 46 If you love those who love you, what reward will you get? Are not even the tax collectors doing that? 47 And if you greet only your brothers, what are you doing more than others? Do not even pagans do that? 48 Be perfect, therefore, as your heavenly Father is perfect.
5 Likewise the tongue is a small part of the body, but it makes great boasts. Consider what a great forest is set on fire by a small spark. 6 The tongue also is a fire, a world of evil among the parts of the body. It corrupts the whole person, sets the whole course of his life on fire, and is itself set on fire by hell. 7 All kinds of animals, birds, reptiles and creatures of the sea are being tamed and have been tamed by man, 8 but no man can tame the tongue. It is a restless evil, full of deadly poison. 9 With the tongue we praise our Lord and Father, and with it we curse men, who have been made in God's likeness. 10 Out of the same mouth come praise and cursing. My brothers, this should not be. 11 Can both fresh water and salt water flow from the same spring? 12 My brothers, can a fig tree bear olives, or a grapevine bear figs? Neither can a salt spring produce fresh water.
1 Therefore, I urge you, brothers, in view of God's mercy, to offer your bodies as living sacrifices, holy and pleasing to God--this is your spiritual act of worship.
