Ephesians 4:15,29,32

15 but speaking truth in love, we may grow up in all things into him, who is the head, Christ; 

29 Let no corrupt speech proceed out of your mouth, but such as is good for building up as the need may be, that it may give grace to those who hear. 

32 And be kind to one another, tenderhearted, forgiving each other, just as God also in Christ forgave you.
