James 3:10 (NKJV): Out of the same mouth proceed blessing and cursing. My brethren, these things ought not to be so.
James 3:1-12 (NKJV):My brethren, let not many of you become teachers, knowing that we shall receive a stricter judgment. 2 For we all stumble in many things. If anyone does not stumble in word, he is a perfect man, able also to bridle the whole body. 3 Indeed, we put bits in horses’ mouths that they may obey us, and we turn their whole body. 4 Look also at ships: although they are so large and are driven by fierce winds, they are turned by a very small rudder wherever the pilot desires. 5 Even so the tongue is a little member and boasts great things. See how great a forest a little fire kindles! 6 And the tongue is a fire, a world of iniquity. The tongue is so set among our members that it defiles the whole body, and sets on fire the course of nature; and it is set on fire by hell. 7 For every kind of beast and bird, of reptile and creature of the sea, is tamed and has been tamed by mankind. 8 But no man can tame the tongue. It is an unruly evil, full of deadly poison. 9 With it we bless our God and Father, and with it we curse men, who have been made in the similitude of God. 10 Out of the same mouth proceed blessing and cursing. My brethren, these things ought not to be so.11 Does a spring send forth fresh water and bitter from the same opening? 12 Can a fig tree, my brethren, bear olives, or a grapevine bear figs? Thus no spring yields both salt water and fresh.
Matthew 12:33-37 (NKJV):
James 1:21-26 (NKJV):Therefore lay aside all filthiness and overflow of wickedness, and receive with meekness the implanted word, which is able to save your souls.22 But be doers of the word, and not hearers only, deceiving yourselves.23 For if anyone is a hearer of the word and not a doer, he is like a man observing his natural face in a mirror; 24 for he observes himself, goes away, and immediately forgets what kind of man he was. 25 But he who looks into the perfect law of liberty and continues in it, and is not a forgetful hearer but a doer of the work, this one will be blessed in what he does.26If anyone among you thinks he is religious, and does not bridle his tongue but deceives his own heart, this one’s religion is useless.
James 1:19 (NKJV): So then,[a] my beloved brethren, let every man be swift to hear, slow to speak, slow to wrath.
2 Corinthians 10:5 (NLT): 5 We destroy every proud obstacle that keeps people from knowing God. We capture their rebellious thoughts and teach them to obey Christ.
Matthew 12:34 (NKJV):Brood of vipers! How can you, being evil, speak good things? For out of the abundance of the heart the mouth speaks.
Acts 8:9-25 (NKJV):But there was a certain man called Simon, who previously practiced sorcery in the city and astonished the people of Samaria, claiming that he was someone great, 10 to whom they all gave heed, from the least to the greatest, saying, “This man is the great power of God.” 11 And they heeded him because he had astonished them with his sorceries for a long time. 12 But when they believed Philip as he preached the things concerning the kingdom of God and the name of Jesus Christ, both men and women were baptized. 13 Then Simon himself also believed; and when he was baptized he continued with Philip, and was amazed, seeing the miracles and signs which were done. The Sorcerer’s Sin 14 Now when the apostles who were at Jerusalem heard that Samaria had received the word of God, they sent Peter and John to them, 15 who, when they had come down, prayed for them that they might receive the Holy Spirit. 16 For as yet He had fallen upon none of them. They had only been baptized in the name of the Lord Jesus. 17 Then they laid hands on them, and they received the Holy Spirit.18 And when Simon saw that through the laying on of the apostles’ hands the Holy Spirit was given, he offered them money, 19 saying, “Give me this power also, that anyone on whom I lay hands may receive the Holy Spirit.”20 But Peter said to him, “Your money perish with you, because you thought that the gift of God could be purchased with money! 21 You have neither part nor portion in this matter, for your heart is not right in the sight of God. 22 Repent therefore of this your wickedness, and pray God if perhaps the thought of your heart may be forgiven you. 23 For I see that you are poisoned by bitterness and bound by iniquity.” 24 Then Simon answered and said, “Pray to the Lord for me, that none of the things which you have spoken may come upon me.”25 So when they had testified and preached the word of the Lord, they returned to Jerusalem, preaching the gospel in many villages of the Samaritans.
