Eliminate those things that do not pertain to the will of God

God’s Word will not misguide you.  His Word will cleanse you from unrighteousness.  

That ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts; Ephesians 4:22 KJV

And be renewed in the spirit of your mind; Ephesians 4:23 KJV

And that ye put on the new man, which after God is created in righteousness and true holiness. Ephesians 4:24 KJV
