Off with the Old and On with the New. 

1. Put off the Old Man and Put on the New. 
Ephesians 4:22  That ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts; Eph 4:23  And be renewed in the spirit of your mind; Eph 4:24  And that ye put on the new man, which after God is created in righteousness and true holiness.

2. Be Honest 
Ephesians 4:25  Wherefore putting away lying, speak every man truth with his neighbour: for we are members one of another. 

3. Be Angry but don’t sin.
Ephesians 4:26  Be ye angry, and sin not: let not the sun go down upon your wrath: Eph 4:27  Neither give place to the devil. 

4. Be a giver not a taker.
Ephesians 4:28  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.  

5. Attack the problem not the person. 
Ephesians 4:29  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. Eph 4:30  And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption. 

6. Act don’t react.
Ephesians 4:31  Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice: Eph 4:32  And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you.
