Today’s Scripture reading is Ephesians 5:18-21.
Verse 20 - "Giving thanks always for all things unto God..."
Being thankful shouldn’t be a new concept to born again believers.  This could also be said for the unsaved.  There are two words in Ephesians 5:20 that take the concept of thankfulness to a new level.  Those two words are always and all.  These two words leave no room for being unthankful.  We read in 1 Thessalonians 5:18, "In every thing give thanks: for this is the will of God in Christ Jesus concerning you."  
This would be a good day to start being thankful all the time.  Start with thanking the Lord for your salvation!
