Only let your conversation be as it becometh the Gospel of Christ... (Philippians 1:27)

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 neighbor...(Ephesians 4:22-25)
