After your kids read John 15, select a broad, blank wall. Have the kids paint the wall with a high quality background paint. After this dries, sketch a vine, as they think it should look, across a portion of the wall. Leave room for the vine to lengthen, and room for verse 5 to explain to viewers what is being attempted. Have your young people paint the vine in colors appropriate for vines, writing verse 5 in large letters, and leaving space around the vine for the names of all your kids, both now and in the future. Have your young people write their names in charcoal, attached to the Vine where the students think is best. Go over the letters in high quality black paint. You will have a visual representation of the relationship youth groups are trying to build.
