Thanks for asking a question on www.thisisyourbible.com
The passage on which you based your question is Ephesians 5:18 not 6:18
Eph 5:18 And do not be drunk with wine, in which is dissipation; but be filled with the Spirit, [NKJV].
The NIV translates the same word as "debauchery" and the KJV uses "excess".
The Greek word translated "dissipation" in the NKJV is: asotia and means riotous living or debauchery. In English, to dissipate is to gradually disappear or waste away with no positive result. Dissipation is usually associated with the sins of idleness, drunkenness, and sexual excess.
