Some time ago there was an elaborate post on the use of LEGO® SERIOUS PLAY® in Church groups that you can read here
Its author Kaj ten Voorde has in the meantime built an English language dedicated website for this at www.themakingofmeaning.com.
The details of the site are the following.
Using LEGO® to help with constructing the meaning of the Bible and faith for your life and church. That’s what The Making of Meaning is all about. Go one step further during Bible Study, the Alpha course, in Church Small Groups, workshops, vision-meetings, and engage your senses. A new world appears before your eyes when boxes of LEGO® hit the table. You will practice with metaphors, your hands will visualize, your thoughts will reflect and the Bible and faith will gain a whole new sense of expression. The Making of Meaning is based upon his graduation thesis of the same name. Discover what The Making of Meaning has to offer you and your church.
