At home group last night the songs reminded me of Eph. 2:10...we are called God's 'masterpieces', then thought of the other portions of Ephesians 1 and 2 I had written along with John 17:23 & 1:12. I shared how I had found the note written in 1991 and realized how much the words I had jotted on a 
3" x 5"  card about how a handful of men who had seen the Father by spending time with Jesus and then turned one of the greatest empires in history upside down fit with the truths from John 17:23 and Ephesians:    

John 17:23 (New Living Translation)

²³ I am in them and you are in me. May they experience such perfect unity that the world will know that you sent me and that you love them as much as you love me.
