Ephesians 3:17-19 is a popular choice. The print can be bought on etsy. The version below is from the New Century Bible, a simplified Bible text aimed at children with limited vocabulary skills, much like the Gleason’s New Life Bible. Recently, the NCV text was combined with The Youth Bible and updated in 2007.
17 I pray that Christ may live in your hearts by faith. I pray that you will be filled with love. 18 I pray that you will be able to understand how wide and how long and how high and how deep His love is.
19 I pray that you will know the love of Christ. His love goes beyond anything we can understand. I pray that you will be filled with God Himself.
20 God is able to do much more than we ask or think through His power working in us. 21 May we see His shining-greatness in the church. May all people in all time honor Christ Jesus. Let it be so.
