This I say therefore, and testify in the Lord, that ye henceforth walk not as other Gentiles walk, in the vanity of their mind, having the understanding darkened, being alienated from the life of God through the ignorance that is in them, because of the blindness of their heart: who being past feeling have given themselves over unto lasciviousness, to work all uncleanness with greediness. But ye have not so learned Christ; if so be that ye have heard Him, and have been taught by Him, as the truth is in Jesus: that ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts; and be renewed in the spirit of your mind; and that ye put on the new man, which after God is created in righteousness and true holiness. Wherefore putting away lying, speak every man truth with his neighbour: for we are members one of another. Be ye angry, and sin not: let not the sun go down upon your wrath: neither give place to the devil. Let him that stole steal no more: but rather let him labour, working with his hands the thing which is good, that he may have to give to him that needeth. Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers. And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption. Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice: and be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ’s sake hath forgiven you.” Ephesians 4:17-32 9KJV)
Put off the “old man” that old nature and put on Christ. When a man, woman, boy or girl comes to faith in Jesus Christ we are changed into the likeness and image of Christ; therefore we are to live like Jesus Christ. Far too often I hear professing Christians who speak corruptly; and that is not only vulgarity in the form of cursing, or what we may think of as bad language; that includes the ridicule of another individual, or showing them as being worthless.
Let us follow the way of Jesus Christ and live.
