Eph 4:29-31, 29 Let no corrupt word proceed out of your mouth, but what is good for necessary edification, that it may impart grace to the hearers. 30 And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption. 31 Let all bitterness, wrath, anger, clamor, and evil speaking be put away from you, with all malice.
Put off corrupt words. Let no corrupt communication, what is rotten, anything that will demoralize others control you. All that the Christian speaks should be that which is good to the use of edifying, building the hearers up in Christ. Slander, gossip all tear rather than build, Solomon’s words of wisdom, “Keep your heart with all diligence, For out of it spring the issues of life.” (Pro 4:23). Put on edifying spirit.
In addition and even greater, grieve not the Holy Spirit. Such sins as those described above grieve the Holy Spirit and He will not continue to dwell in those addicted to them. It is important that we pursue that which is good, that is truth instead of falsehood, gentleness over anger, earnest toil for dishonesty, cleansed instead of filthy speech. If all believers were to live like this, the world would know that the Son of God has come and lives in us. It is not enough that a man should believe to secure deliverance from the wrath of God; he must daily seek to attain to such resemblance of Jesus in words, thoughts, and deeds.
